How to rid of annoying "beep" sound??!!

[javaguy216]

I don't think this is a PC, USB, or a sound card issue. I have a friend who uses an ATA and he is experiencing same issues/problems. Around 10 to 15 min into the phone call, it sounds like someone is pressing a key. I think the problem is on MJ side.

Java,

I agree with you completely !!!

How old is you MJ?

My daughter and I just with in the month purchased new units (I don't know how to determine the Rev level) but "knock on wood" the problem has for the moment anyway disappeared.

[javaguy216]

HolmanGT,

My friend's MagicJack is less than a 1 month old. Mine is almost a year and I don't have any issues. I tried to troubleshoot his MJ, but we couldn't figure it out. I did eliminate the actual phone, MJ itself, or any issues associated with PC since he is using an ATA. I tried to get some support from MJ Tech support, but like having tits on a bull, useless!

[Magicjackernc]

Mine is brand new...received it about a week or so ago.

I'll keep checking this thread for a fix. So if anyone ever comes across one- please post.

Magicjackernc,

A lot has been revealed in this thread albeit none of it is a fix in and of itself.

What I would suggest is (God I hate to say this) get with the Tech Chat folks and don't do anything they ask you to do just play along. If you follow their instructions when you get through you will have a MagicJack that still doesn't work and a computer to match.

That out of the way, beg, plead, grovel, do whatever you have to do to get your case oscillated to the next level Technician and then start the begging and groveling again asking for someone to please reset your account on their servers.

I am very suspicious that this is where a potential solution lies. I at first thought the new MJ I sent my daughter fixed her Touch Tone problem but now I don't thing that had anything to do with it.

But she did register it and took a new number i.e. a new account this should be the same thing as resetting your account (or close to).

In any case you don't have to be a rocket scientist to tell from this post that it has absolutely nothing to do with the MJ device itself nor the computer it is or is not plugged into (as in one example here).

PS - I think she is going on three weeks now with the new unit/account and we talk almost every night and "knock on wood" not one single beep, boop, touch tone or squeal. And I know I am repeating myself, but the audio and "Full Duplex" is better than it has ever been. Admittedly I don't understand what in resetting an account could account for this behavior but it sure looks like something when corrected on their end corrects a lot of things on our end.

Maybe I can shed some light on this. I had a VoIP phone (TomatoVine) which had this same problem. I posted on the DSLReports website and was told that this is a common problem. I can't remember what it was called but it has to do with the way touch tones are detected by VoIP phones.

Some people's voices, usually females, when they say certain words or letters hit the frequencies that trigger the DTMF tones you are hearing. This can be helped I am told but at the expense of sending Touch Tones over the VoIP phone.

When I would talk to my wife over my VoIP phone I would hear tones when she would say certain words, she would not hear the tones.

This might be what you are hearing.

domiii,

OK now that you have brought it out in the open, from day one I thought it had something to do with my Daughters voice especially if she was talking loud.

It also does not surprise me that someone with the right tonal qualities to their voice could fool a Tone Decoder into thinking it just received a Touch Tone and immediately echos it back out to the receiving party.

Now that there are two of us... well that is going to be my story and I am going to stick to it until they laugh us both out of town on a rail.

My sincere appreciation for you post, I never would have had the nerve to come out and say it first.

Regards, Mr. domiii

Interesting.... Very interesting.... But I guess I am wondering why this problem occurs on the "newer" MJ accounts, and not on the older ones?

[HolmanGT]

Newer or Older accounts

In my daughters case it only happened with her original "Older account, phone number and device. With her original account, new number and new MJ device it does not happen anymore (at least not so far "knock on wood").

I don't think this is anything we the end users are going to figure out or solve. IMHO it is purely an MJ problem, whatever the hell is causing it.

[newtoncd]

We recently starting having the same problem with the tone. The people we are talking with only seem to notice it when my wife is using the phone, not me. I use a T5710 with a device ordered in July.

I noticed on the magicJack keypad, numbers are actually showing up on the display.

I hope it is okay to post a link to the jpg screen capture I took.

NewtonCD,

I have a post right above yours that claimed the problem was solved, please excuse me for not updating it.

The problem is not cured but it is less frequent then it was. As in your situation it only happens when my daughter is speaking and only I hear it.

Someone else on here suggested they believed it was being triggered by a female voice. I had that suspicion for quite some time with her older MJ device but didn't have the "Cough" to suggest my suspicion for fear of being laughed off the forum.

One important, or I think it is anyway, item that I have never seen posted about this problem is the fact that your softphone is displaying the numbers also. I think I will see if it shows up on my cordless phone display. Most of the time when I am talking to my daughter I am outside or in the garage (depending on the temperature) have a smoke, plus I hardly ever watch what the softphone is doing. I may have to make an exception and try watching it the next time my daughter and I are conversing.

Anyway Mr. Newton you are not alone and to date I have not heard many people mention this problem and for sure have not read anything that hints of a cure/FIX.

Thanks for the post and the screen shot, it helps to alleviate the feeling I was just losing it. (OK Mr. AZ that is not a straight line for a shot across my bow )

PS - Welcome aboard the "Good Ship Lolly Pop" I don't know if anyone will have an answer to this problem you are having but there is probably more MJ expertise on this forum than any of the others.

[grw]

I will join the beep crowd.

I just spent several minutes on MJ with a friend who complained about the beeps he heard on his end. I didn't hear anything at all on the MJ end of the conversation.

This is the first time anyone I have talked with via MJ has said anything to me about the beeps. It may be an intermittent problem.

[newtoncd]

PS - Welcome aboard the "Good Ship Lolly Pop" I don't know if anyone will have an answer to this problem you are having but there is probably more MJ expertise on this forum than any of the others.

I got on the tech support chat and they had me uninstall the device and let my T5710 reinstall it on the next reboot. I can't see how that will fix it, but I gave it a shot.

More to follow.

I also emailed Dan, but haven't heard anything back.

[TooManyIDs]

Looking for a "touch tone sound" fix as well.

[HolmanGT]

Newton & TooMany,

I am going to take a few wild stabs here but first let me say that this problem has been attributed to everything including a full moon and is generally associated with a womans voice. Often times when this problem is posted it will go like this; "When I make a call it doesn't do it but when my wife uses the phone she has the problem almost always". Anyway for what it is worth I lean heavily toward the female voice triggering the touch tones. So if you two guys are "Guys" don't be offended, please, some voice qualities can trigger this anomaly and it doesn't have to be a female voice but it helps.

OK Here is what I would try:
1. Make sure your send and receive volumes in the soft phone are set to no more than 1/3 the way up from the left side.
2. In your PC's sound setting make sure the microphone boost is unchecked in both record and playback and additionally I would also check the mute button for the microphone.
3. Back in the MJ softphone go to headset an microphone if you are not using it and turn the volumes to zero.

For what it is worth my daughter has had this problem from day one, several hardware revisions and software revisions back.

I have tried everything to eliminate it, I really mean everything. The suggestions I made just above helped and it very seldom happens to her any more but is still happens occasionally, especially if she get excited and over-talks the phone too much. With her system I am 100% convinced that it is something in the tonal qualities of her voice that trigger the touch tones and that is not to preclude MJ's responsibility in this. In truth it is something a little to sensitive on their end but you are never going to get them to admit to it. The truth is they just play dumb when you bring up something like this. OK I am lying they are not "playing".

Because I have done the following:
1. Purchased the latest hardware version for her.
2. Changed the computer she runs on, T5720 Thin Client, now.
3. Changed her MJ phone number with a new contract, couldn't get the tech people to reset her account so I did it the hard way.
4. She is DSL, I did have some suspicions about that and maybe still do, but she has even moved to another part of town so she is on a different DSL trunk.
5. This item represents all the things I did and can't remember, but if it could be changed for the sake of testing believe me I changed it.

George and Newton

Is there a chance that going to the sounds and audio devices portion of the control panel and then turning off some/all of the sounds that are windows generated would make a difference ?

[HolmanGT]

George and Newton

Is there a chance that going to the sounds and audio devices portion of the control panel and then turning off some/all of the sounds that are windows generated would make a difference ?

CD,

I personally defeat or turn to zero the volume of all the controls that are not needed for my audio devices... WAV, MP3 and Windows sounds on a regular PC. On a thin client i turn them all off, they don't seem to be needed for MJ to function correctly. The only reason I turn them all off is I don't know if they cause internal feed back loops or not so just turn them off to be safe and hope that it helps.

But as I have said nothing has completely eliminated the problem on my daughters machine, but it is much, much better with the setting I mentioned and the ones you just got me to admit to. Now I will hear the touch tones from my daughter machine maybe once in ever three conversation. Her problem used to be several in every conversation.

To tell you the truth, there is nothing scientific about what I have done. I just through the dice. The rest is up to God and MJ (God and MJ are used in the same sentence but not to indicate any relationship whatsoever).

[newtoncd]

I have turned the volume down on the softphone, no joy.

However, I can't confirm this yet, but it looks like when my wife uses the phone in non-speaker phone mode, the distant end doesn't hear the beeps.

Today: I had her try a test with our Panasonic phone. She talked for 47 minutes, the first 27 on speakerphone, the next 20 in normal mode. On speaker phone, there were 9 beeps; when she wasn't on speakerphone, there weren't any beeps.

More to follow.

If it is one of the Panasonics with the option for voice enhancement, just for kicks you should try your wifes voice on the Panasonic with the enhancement turned on. It wouldn't surprise me if the problem returns.

The newer panasonics in normal mode have some pretty fancy noise cancellation going on. I don't know what you were using for a mike in the speaker phone mode of MJ but I'll bet it doesn't have the same noise limiting characteristics as the panasonic.

The only other alternative is to switch to the Gay side and acquire a male spouse - albeit the problems that come with that may make the touch tone problem look insignificant. Just one of those crazy thoughts - Psychiatrists call them free floating thoughts. Makes ya wonder don't it.

[newtoncd]

I knew I wasn't clear on that. We are using the Panasonic KX-TG9331T phone with 4 satellite handsets.

Most of the time, she uses the speakerphone portion of the Panasonic handset and that is when the distant end hears the beeps.

However, today, when she spoke into the Pansonic handset without the speakerphone, the distant end didn't hear any beeps.

Again, this was just one phone call, we will see if it lasts.

Oh - OK, I did misunderstand you. Does it ever do it when you use the phone in either mode? Also try turning on the Voice Enhancement, I'll bet the ups the number of touch tone events considerably - Just a curiosity thing and it will let you know if it is related to a spectral range or not. May also explain why women and some phone brands have more problems with this phenomenon than others.

[Your Grandfather]

I have 2 magic jacks. One works flawlessly. The other is marginally acceptable. Each Magic Jack is on it's own computer, that does nothing more than host the magic jack.

I have a T1 line inbound which feeds 9 computers. 6 Mac's and 3 windows boxes.

To resolve the problem with the problematic magic jack I have done everything I can think of. Change the computer, change the port on the Firebox. Change the ethernet cable. Change the type and manufacturer of handset. Turned off screen saver. Replaced the magic jack with a new magic jack.

All of this, plus this thread, leads me to believe that the problem is on their side and not at all related to women's voices. Remember we are dealing with DTMF _ Dial Tone Multi Frequency _ so for a voice, male or female, to activate the switch, the voice would have to do multi-frequencies at the same time. Impossible for humans to vocalize two exact tones at the same time for the prescribed time period which the switch requires.

Therefore, the problem has to be at their end, and I'm sure they are reluctant to fix it. (If they know what the problem is).

Given that many people have no problems, I would suggest the problem resides somewhere in the ANI part of their switch.

An idea would be to compile a list of area codes and the next 3 digits. If people in the same area code and exchange are having problems then we can be 100% sure where the problem resides and therefore fix the problem by either getting a new area code or exchange number.

If I had to bet, I would place my 2 cents on the exchange and not the area code.

So, to start out. My area code is 312 and the exchange is 473

[mberlant]

Grandpa,

What happens when you exchange your two MJs? Does the problem move with the marginal MJ or stay with the marginal PC?

OK - first things first, this only happens to me when talking to:
1. to 760-298 California City, CA
2. fr 435-275
3. or fr 435-705 (both MJ(s)) 275 and 705 are for the St. George area UT.

That out of the way "your mother", and purely for the sake of argument, all human speech is simultaneous multi tone primaries, sub-harmonics, harmonics and probably and almost unanalyzable mixtures within the 20-20,000 Hhz range and beyond depending on the person (Yes I realize telephone is 300 to 3000 Hz). Which all mixed together correctly produce the human sounds that people pay to hear at a concert. Do you really think people would pay to listen to a singer with a monotone voice.

I have used plenty of analog and digital tone decoders over the last 30 years and they are not as bullet proof as you seem to think they are. The analog decoders are the worst of course. Hell I don't know maybe YMAX still has some analog decoders buried in their system in some areas. Also they are all subject to false decodes in proportion to:
1. The decoders quality.
2. Analog type
3. Digital type
4. The quality of the audio fed to them.
5. The strict control of the audio levels fed to them.
6. And probably a lot of others things that can come up to haunt the best laid plans.

You say a persons voice can't trigger a touch tone, then you have forgotten the telephone phreaking days when the M$ kids, the Apple kids and a bunch of other telephone phreakers used to get together and watch "Captain Crunch" (moniker for anonymity) "whistle" up free phone calls on public or private phones (then they invented the blue box and no longer had to depend on Captain Crunch's whistling ability.

Offensive comment number two. You say you have a T1 line, OK. But should you really brag that you have it severally overloaded? A T1 these days is one notch below two cans and a string. 1.5 mbps at best. Low end DSL does that. With the number of computers you have hanging on that poor T1 ... well you're lucky it works at all, if all the computers are being used at once. You really need a T2 or better.

In short if Captain Crunch (whom by the way did jail time for his activities, whistling and blue-boxing) could whistle up a telephone number it is very possible that many people may have voice tonal qualities close or right on an existing touch tone pair. After all we are in the USA talking about 300,000,000 plus voices each of which all are unique. I sure would hate to attempt a tone decoder system that could handle that gauntlet.

[mberlant]

Sorry, George, but T1 (1.54 Megabits per second, with a big M) is plenty to handle 9 devices in a SOHO environment. T2 (2.048Mbps), if you can find it, would only offer 1/3 more bandwidth. I operated for years with 7 devices on 768kbps SDSL without any problem, including being able to run Asterisk with as many as 6 simultaneous talk paths. And, this was in the day when G.711 was the only popular CODEC, taking up 80kbps per talk path. I would expect that Grandpa could have 10 conversations going and still not impact communications on his other devices.

As for humans not being able to trigger a DTMF tone, of course they can! An even more common scenario than the one you offered is this - two people are talking on the phone at the same time and one hits one half of the DTMF while the other person hits the other half. No need for extraordinary whistling capability, and the odds of occurrence just increased dramatically.

Heck, about 20 years ago, before CPC became ubiquitous, you could force the conversation to disconnect just by singing "Happy Birthday to You" in a particular key. I knew someone back then who sang in a key such that when he hit the word 'you' for the second time the tone was a perfect 2713Hz held for more than 1/2 second, which triggered the 1AESS to drop the call. He came to me befuddled that he couldn't successfully deliver his birthday greeting to his girlfriend overseas.

p.s. I agree that 1.5 millibits per second (small m) would be pretty hard pressed to handle the load. I don't know how you manage to keep afloat with only 10 millibits per second downstream and 1 millibit per second upstream.

[HolmanGT]

mberlant,

I never knew you could make a phone disconnect via a tone sequence, I find that very interesting. Now I am trying to dream up a method of employing that to give someone a bad time, you know walk up behind them while they are in a business call in their cubicle with a little pocket tone generator... very cool until the person gets wise and kills me.

As far as the little "m" all I have to say is picky, picky, picky! Heck I have enough trouble with "B" verses "b" ... and sometimes I get so annoyed with it I just let it all slide and go lower case just be cause I am lazy. But your are correct about 1.5(4) milli bits/sec being a tad bit slow.

On the speed issue I don't doubt that the T1 line would support seven or so VoIP conversations, but I still have my reservation about it handling seven machines with one or two parties attempting major down loads (I know that is what QoS if for).

When I worked at Corning Glass in Kentucky there were many times I would have to down load a major update package from Allen Bradley or something similar and would have to set the down load to execute just before I left for the night. If I attempted to do it during normal work day it would take forever. Actually I used to go home a lot at lunchtime make the down load and be back to work in no time. I don't know what Corning had for an Internet backbone and we did have several hundred people with access to the Internet so I am not exactly comparing apples to apples here but when I read the seven computer on something that only has 1/10th the capabilities that I have here at home all I could think of was SLOW.

Anyway mberlant, I will try to watch my little "m" and capitol "M" a little closer in the future.

I have just the same experiences as you. I recall setting up overnight jobs both on account of poor network speed and on account of poor PC speed.

Well George,

Here is your quote for a T1 line:
Offensive comment number two. You say you have a T1 line, OK. But should you really brag that you have it severally overloaded?

With the number of computers you have hanging on that poor T1 ... well you're lucky it works at all, if all the computers are being used at once. You really need a T2 or better.

And here is the 'real' answer:
A T1 line can carry 24 digitized voice channels. Put that into your pipe and smoke it.

Secondly, do you honestly believe that 'normal' people can speak into the 20Mhz range? all human speech is simultaneous multi tone primaries, sub-harmonics, harmonics and probably and almost unanalyzable mixtures within the 20-20,000 Hhz range and beyond depending on the person
I'd be willing to be a devalued US dollar you can't hear 20,000 cycles.

Which all mixed together correctly produce the human sounds that people pay to hear at a concert. Do you really think people would pay to listen to a singer with a monotone voice. Not even worth a comment.

You say a persons voice can't trigger a touch tone, then you have forgotten the telephone phreaking days when the M$ kids, the Apple kids and a bunch of other telephone phreakers used to get together and watch "Captain Crunch" (moniker for anonymity) "whistle" up free phone calls on public or private phones (then they invented the blue box and no longer had to depend on Captain Crunch's whistling ability. Yep, I say that, and I stick by it. Being able to correctly whistle a single tone is not the same as being able to whistle two precise tones at the same time. A box is not the same as a person. Box=something that is not a person; A person=something that is not a box. Better get your stuff together before you call someone out. http://www.robson.org/gary/writing/phreaking.html

So, at the end of the day, I stand by my comments since they are rooted in fact and not fiction. If you can document someone who can whistle or speak in 2 very distinct frequencies at the same time. Post the link. If not STFU and stick to stuff you actually know to be true and not a figment of your imagination.

FYI, I was installing ESS at AT&T while you were shitting in your pants and waiting for your mom to change them.

[mberlant]

FYI, I was installing ESS at AT&T while you were s__g in your pants and waiting for your mom to change them.

And I was programming those IBMs in WE clothing while you were installing them. So, what? We're still all here together trying to extract as much service as possible and minimizing as much as pain as possible from the magicJack.

p.s. Back then, I was able to hear above 20kHz. Department store surveillance cameras that squealed at 15,750Hz (monochrome) or 15,734.26Hz (color) were irritating to me at the time. Now, my hearing doesn't quite reach 17kHz, but it's not receding as quickly as my reading vision.

[HolmanGT]

Well George,

Here is your quote for a T1 line:
Offensive comment number two. You say you have a T1 line, OK. But should you really brag that you have it severally overloaded? A T1 these days is one notch below two cans and a string. 1.5 mbps at best. Low end DSL does that. With the number of computers you have hanging on that poor T1 ... well you're lucky it works at all, if all the computers are being used at once. You really need a T2 or better.

And here is the 'real' answer:
A T1 line can carry 24 digitized voice channels. Put that into your pipe and smoke it.

T1 and up is the terminology for digital, two-way transmission of voice, data, or video over a single high-speed circuit. The transmission rate is based on the bandwidth for one voice channel in digital form. This channel is called DS-0 and consists of 64 kbps of bandwidth.
By Time Division Multiplexing 24 DS-0 channels, T1 is formed. But there is more. To separate the different channels a framing bit is used. For framing 8000 bps are used.
T1 gives you 24 analog voice channels plus the framing rate. This makes the T1 speed: 24 x 64000 + 8000 = 1.544 Mbps. For the other T-versions an equal equation is used ending everything up to the specs given in the table below. Should we move on to something everyone doesn't already know?

Secondly, do you honestly believe that 'normal' people can speak into the 20Mhz range? In kHz yes I do and some operatic singers may even go higher. all human speech is simultaneous multi tone primaries, sub-harmonics, harmonics and probably and almost unanalyzable mixtures within the 20-20,000 Hz range and beyond depending on the person

Do you have any concept of frequency mixing. 8,000 Hz mixed with 12,000 Hz will produce the sum, difference and the two originals, guess what the sum is. This is obviously a principle you do not comprehend.

I'd be willing to be a devalued US dollar you can't hear 20,000 cycles.


As far as my hearing abilities I don't ever recall mention my hearing range. My reference to the 20 Hz to 20,000 Hz was only be because the is considered optimum limits of human hearing. The same deal with 300 to 3000 Hz being consider the required limits for telephone bandwidth (not to be exceeded).

Which all mixed together correctly produce the human sounds that people pay to hear at a concert. Do you really think people would pay to listen to a singer with a monotone voice. Not even worth a comment.

"Not worth comment" that's a shame, I thought it to be extremely pictorial in nature.

There is nothing in your link that denies my claim about Captain Crunch, be it a single tone as in the article you were so kind to link to or multi-tone. No one else in the group was able to do it because as any musical instrument a whistle tends to put out (here we go again) sub-harmonics, harmonics, the sum, difference and the two originals of all the harmonic content. We are not talking rocket science here just normal acoustical physics. Oh and tanks I wasn't 100% sure it was Captain Crunch that did the whistle thing, could have been one of the others - just took a gamble.

So, at the end of the day, I stand by my comments since they are rooted in fact and not fiction. If you can document someone who can whistle or speak in 2 very distinct frequencies at the same time. Post the link. If not STFU and stick to stuff you actually know to be true and not a figment of your imagination.


http://en.wikipedia.org/wiki/Timbre i.e. multiple tone from a single voice or instrument.

The richness of a sound or note produced by a musical instrument is sometimes described in terms of a sum of a number of distinct frequencies. The lowest frequency is called the fundamental frequency and the pitch it produces is used to name the note. For example, in western music, instruments are normally tuned to A = 440 Hz. Other significant frequencies are called overtones of the fundamental frequency, which may include harmonics and partials. Harmonics are whole number multiples of the fundamental frequency — ×2, ×3, ×4, etc. Partials are other overtones. Most western instruments produce harmonic sounds, but many instruments produce partials and in-harmonic tones, such as cymbals and other non-pitched instruments. A not so technical analogy is the beautiful sounding Asian Throat Singer.

Throat singing, a traditional Central Asian art similar to what is sometimes called in the western world overtone singing, harmonic singing, or harmonic chant (terms created by David Hykes in 1975), and many other regional names, is a type of singing that manipulates the harmonic resonances (or formants) created as air travels through the human vocal folds and out the lips. David Hykes (1953 - ) is a musician, composer, author, experimental filmmaker and meditation teacher, and a principal pioneer in the modern harmonic, healing sounds and contemplative chant movements. ... 1975 (MCMLXXV) was a common year starting on Wednesday (the link is to a full 1975 calendar). ... In acoustics and telecommunication, the harmonic of a wave is a component frequency of the signal that is an integer multiple of the fundamental frequency. ... In physics, resonance is the tendency of a system to absorb more oscillatory energy when the frequency of the oscillations matches the systems natural frequency of vibration (its resonant frequency) than it does at other frequencies. ... A formant is a peak in an acoustic frequency spectrum which results from the resonant frequencies of any acoustical system. ...

The harmonic frequencies created by the human vocal apparatus are harnessed in throat singing to select overtones by tuning the resonance in the mouth. The result of tuning allows the singer to create more than one pitch at the same time, with the capability of creating six pitches at once. Generally the sounds created by throat singing are low droning hums and high pitched flute like melodies.


FYI, I was installing ESS at AT&T while you were shitting in your pants and waiting for your mom to change them.

I have worked as an Electronics Communications and Controls Engineering for forty nine years an still do. I have 720 class room hours of training from the U.S. Navy in Electronic Communications and a BSEE from McNeese State University of LA. I don't know why you bring up your longevity as justification to prove your arguments you can be in this world a very long time and still not have a very good education. And the fact that you worked on "Cross Bar Relay Logic", or whatever you mean by ESS is really not very impressive. and if you are as old as you claim that is about all they had "back in the day" for switching analog signals. Big damn deal, I have cleaned the contacts of a few of those beasts myself.

@ Mr. Admin, "Way off Topic Debate there will be no further activity on my part.". (gth)

I had this problem when I used my jack on my thin client.

The thin client had way too many problems so I did a reinstall on my other computer and then I hooked up my jack there and then I loaded the original linksys firmware on my router and now the problem is solved.
