No sound in-or outgoing calls - a firewall issue

[Kaari]

Hello all,
need baddly some help with my new Magic Jack. I searched in these forums but didn't find anything like this:

1) Wired connection to my own DSL router: The phone works (meaning I can dial calls, and the phone rings if someone calls), MJ softphone works, USB/PC (one w XP other w Win7) work BUT there is NO sound at all for incoming or outgoing calls (I can't hear the other end and they can't hear me, no echo either, nothing).
2) Wireless connection to my neighbours unsecure wireless network, both phone and MJ soft phone work great for both incoming and outgoing calls, albeit the sound is a bit choppy.
3) Wired connection to my own DSL, disabled the DSL modem/router firewall, and the phone and MJ softphone work fine for both incoming and outgoing calls and the sound quality is good too.

As I did not change anything else except enabling/disabling the firewall on the DSL modem/router, it seems that the issue is with the firewall on my modem/router (westell versalink 327 yeah I know it's old but it works ). Since I do want to keep the firewall up on the modem/router for security reasons, how can I get MJ to work?

I've talked (well, chatted online) with MagicJack help for several hours, and the last one disconnected me (!!) because I wasn't doing as I was told! I told him that I did not want to remove my DSL router firewall so he disconnected me just like that! Talk about customer service. But I digress.

Since MJ "techs" weren't much help, I'm turning to all of you for solutions. Surely there must be a way to be able to keep the firewall up on DSL router and use MJ at the same time? I did set the port forwarding on the router up with UDP 5060-5070 but that didn't do anything.
Any help would be greatly appreciated!
thanks

This sounds like a port forwarding issue. If you would like to leave the router/firewall enabled, try setting port forwarding on the router/firewall. Typical steps are to log in to the router, on the port forwarding tab (may have to search a bit for it as each router seems to put it in a different place) enter the ports for MagicJack and set them to forward to the ip address of the computer where MagicJack is intalled. This will open a tunnel for the ports needed but keep other ports closed.

Yup it IS a portforwarding issue. And as I mentioned in my original note, I had opened (or forwarded) the ports 5060-5070 on the router firewall. Alas this did not help to solve the issue.
I think there are other ports that need to be opened, not just those ones. Would really appreciate some help with this.
thx

Alancris:
As I mentioned in my very initial post, and also on the reply you replied to, I have already opened the UDP ports 5060-5070 in the router firewall. Doing so didn't solve the issue.

So please if there is anyone else out there who can help me to find out which additional ports (outside the aforementioned 5060-5070 which I already have opened) I really would appreaciate the help!
thx

In addition to UDP on ports 5060 & 5070 MJ uses 80 and 443. But in addition the audio portion of a call is passed using RTP (UDP) on a port normally in the range of 10,000-20,000 although MJ has been seen to use higher ports in the past up to 45,000 as I recall.

A port in this range is normally negotiated between your computer and the MJ server and your router using "Port Triggering" it sonds like something is amis in the port triggering and your router. You could of coarse open up (port forward) that entire range of ports; however if you do why bother having a firewall since you will have defeated most of it. I am NOT familiar with your router so I can't help you any more than that.

BTW often when folks are trying to help you they need you to do certain things in order so they can determine the exact cause of your problem. Some of these things can after a determination of the problem has been found be put back in place. (i.e. temporarily disable anti-virus etc. or place a computer in DMZ) to see if that changes the symptoms and thus points the trouble shooting in the right direction.

If someone had asked for my help and then refused to do something I asked them to do in order to help the trouble shooting I'd hang up on them too!

Thanks, tried opening TCP ports 80 and 443 too, no luck.

Opening all those other ports doesn't sound like a very safe idea. Is this a router issue? Meaning would I have same safety and wouldn't have to hassle with opening ports etc if I had a different router? And if so, which router should I go for?

Firewalls all seem to have different ways to write rules/exceptions. You might look into exactly how you've written it.

Also if you have the capability to view your traffic log, you will get some insight into exactly what is going on...in fact, that's where I'd go first. See exactly what is being blocked.

You could take another approach *YGMMV
Allow by IP address: here's the talk4free.com ranges:
NetRange: 64.0.0.0 - 64.3.255.255
NetRange: 66.104.0.0 - 66.107.255.255
NetRange: 67.88.0.0 - 67.95.255.255
NetRange: 67.104.0.0 - 67.111.255.255
NetRange: 216.234.64.0 - 216.234.79.255

I had the same issue and spend a couple weeks trying to figure it.

My MJ is connected to a Maxspeed 8300 Thin Client. To mange it I remote in from my Windows 7 laptop. I discovered when you start a remote desktop session you should:

1. Click the 'Options' button.
2. Select 'Local Resources' tab.
3. Click the 'Settings...' button.
4. Under 'Remote audio playback' select 'Play on remote computer.
5. Click 'OK'
6. Click 'Connect'
7. Log in to your TC.
8. With the magicJack client running select 'Menu' > 'Volume/Headset Control...'
9. Select the device you wish to use and move the speaker and microphone sliders to the right and close by click 'X'.

Try it out.... it work for me. I use MJ for a second telephone line. So if you manage your MJ thin client via Remote Desktop this should work.

Let me know what you figure out.

Hi,
I had the exact problem with my MJ. And I use a Westell 372w dsl/gateway. I was able to fix it by forwarding ports in the 40000-50000 range. I know this sounds like a lot of ports... but hope this helps

[billyd]

Hello,

Since my last post, I was able to find more info on the port that MJ might use with a Westell router. I don't know why that would be any different than other routers, but here is a refined port number list that works very well for me.

http://www.dslreports.com/forum/r215829 ... -MagicJack

UDP 5070 5070 5070 IN (DST)
UDP 10000 30000 10000 IN (DST)
UDP 49000 50100 49000 OUT (SRC)

I was having problems with no sound with my magicjack, turned out to be my router firewall. My MJ is on a TC so I put it in the DMZ and now my calls are great. I figured if I had to open all the ports I read about here all my pc's would be at risk and since a TC is basically virus proof I'd rather have it exposed.
