An ever increasing time lag occurs

[mat.phillips]

On my little home system, I have a remote extension in another country using an IAX softphone. I use this to talk to a friend as the call quality is better than teamspeak, which we used to use.

During a conversation between that remote extension, and my extension (so technically, an 'internal' call) a time lag starts and grows. So at the start of the call, everything is good, then after a minute or so, what I say takes a second to get the the other end. After a few minutes the lag grows. I've actually had this lag reach around 30 seconds. No voice traffic is lost, and the audio does not seem to be 'slowed down' but the delay in one side hearing what the other side said just grows and grows.

I have checked in the console for everything I can think of, the ping to the remote xtn is good at about 50ms and there seem to be no lost packets.

I cant think of a reason this could happen, and it seems like it couldnt actually happed, I mean asterisk seems to be buffering huge amounts of data and delivering it late? It's very odd.

Anyone have an idea how to go about debugging it? Oh, and if you terminate the call and then dial back right away, its fine again and then drifts out.

You might want to try a different softphone. If you are using Zoiper, I have had little quirky things with it.

I should have mentioned, the softphone in use at both ends is iaxLite version 2.3.0.6

It's a very simple, small app. I can try using something else but I'm still at a loss as to how the app could be creating the problem.

Hi

I saw this a couple of years ago with this problem, but only on one installation - at 16 seconds lag, I had to say "over" at the end of each sentence.

I've not used IAXLite since.
