RE: [Asterisk-Users] Zap X100P oscillation
What is particularly weird is that if I connect a call to Echo on my local server, I don;t usually get this oscillation, however if I connect it to Echo on another Asterisk server (over IAX), it does happen. The main difference will be the delay in the echo, as the software versions are within the last two days. The Echo application is the same on both, and the call should be entirely digital so there should be no gain differences and there is no echo suppression on the IAX link, so it must be the local Zap echo canceller fighting with the apparently longer line?

RE: [Asterisk-Users] Zap X100P oscillation
Thanks for the responses. I have tried it with aggressive cancellation both on and off. I think that on helps a tiny bit. I'm glad that Mike Benoit as seen something similar, but of course sorry that he is suffering like me! It is worse when I have a Phone-switch-X100P-IAX-Internet-IAX-X100P-switch-Phone link set up. The other thing which may have helped a bit is using a large set of IAX Jitter buffers. It may be the latency which is helping though, rather than the anti-jitter aspects.

RE: [Asterisk-Users] Zap X100P oscillation
I find that if I drop the RX gain too much I start to lose DTMF decoding. The Asterisk calls lose at least 3-6db end-to-end compared with a normal call. If I bring the gain up, the symptoms sound exactly like yours. The gain I am using is more like Rx=-2, Tx=0 but this is still quite quiet. I guess that line impedance mismatch between US and European standards accounts for some of the gain loss.

Re: [Asterisk-Users] zap x100p
Thanks for the answer. I only joined the list 4 days and did not mean to ask a reduntant question. I will see if I can get it fixed. I assume turning callerid would not make it wait for that, so the shortest amount of time might be 1 to 2 rings then? Any tips on debugging callerid problems?
