Delay

[rodak]

Hi. I've been using my MJ for a few weeks, and am fairly satisfied. Thanks to the information I've found here, I think I'll be able to deal with the voice choppiness I experience sometimes.

Right now, though, one thing that concerns me is the delay I'm experiencing. I'd have to say it's in the neighborhood of 200-300ms each way, which is roughly a half second total. This makes for a lot of stumbling when carrying on conversations (a lot of pauses and "...no, you go ahead.."). No one I've talked to has complained, but it bothers me, and I've had to very carefully pace my talking and listening habits.

Is this normal? Is there anything that can be done? I called the echo test number (909-390-0003), and hear about a full half-second delay between me talking and hearing my voice back. Is that normal, or should it be immediate (guess I need to try it on my landline).

Call with you cell phone ... how's the delay?

HI,

I also noticed a delay when speaking. Nothing that stops me from using my MJ but enough to make conversations a bit awkward at times.

I've done a number of things to try to minimize this, i.e. dedicated server, not using anything wireless, not running anything else on the network, QOS, etc. but this doesn't seem to help (though it did improve sound and service) . I was starting to think that this was a MJ issue but then our office switched to a high end Nortel VOIP system and I experienced a bit of a delay. In fact I've had a number of dropped calls and audio issues.

This makes me think that my issues with MJ are actually issues with VOIP.

I'd like to hear from anyone who feels that there isn't a delay. Maybe they could share their spec's with us.

Calling from my cellphone to the echo test number yields a small delay, maybe 200ms or so. calling from my cellphone to/from my MJ I hear about the same amount of delay (which is how I discovered it was even happening)

That's real interesting. Our office is also going VoIP soon, using Avaya gear. I'll keep this in mind when we finally get it in place.

I think I've always had a 200ms delay. That doesn't sound unreasonable. A 500ms delay might start to be.

You could determine your proxy and then try:

Code: Select all

traceroute proxy1.{cityname}.talk4free.com
traceroute vms1.{cityname}.talk4free.com

If you have a large number of hops due to bad network routing, that could make it worse. (But, when I'm in South America using MJ, I don't notice an increased delay. Not much.).

You can replace {cityname} with major cities near you. It's not easy to discover the proxy server your softphone uses. As far as I know, you have to use wireshark to trace MJ when you start, get the IP address for the SIP connection. Then nslookup that IP address to get the hostname.

I'm pretty sure the echo number introduces a delay just so there will always be adequate delay for its purpose (to echo what you say back to you). I don't believe it's representative of the delay that would exist during a regular call.

As you said, you should try it on a landline and cellphone (that are in your presence). Clap your hands and see how long it takes to hear it on the other phone.

I suppose you could test it with someone remotely. Agree that you'll say "one". The other person should say "two" as soon as they hear it. Divide the amount of time it takes for you to hear "two" in half.

I have the same problem with delay. It's the only thing that keeps me from using my magicjack very much.
