[Asterisk-Users] Incoming IAXTel/IAX2 issue

[Ben Witso]

Hi all,

I spent most of the last weekend testing and trying to diagnose some 
mostly incoming call issues. I'll start with the easy one in the hopes 
it might have a positive impact on the others. First- I have an account 
with IAXTel. I can place calls to other IAXTel subscribers and also 
through IAXTel to landline toll free numbers and all works great. iax2 
show registry shows I am successfully registered with IAXTel. I wanted 
to test my incoming IAXTel connection so I thought I'd call myself. The 
first time I did, the call came in and played about 1 second of the 
audio from my 1st speech file and about 1 second of the 2nd but was 
silent the rest of the time. You could see from the console that the 
call was progressing, and it wound up dialing the extension I had 
programmed - I just couldn't hear anything. On subsequent calls I could 
hear no audio at all even though the call processes as it is supposed 
to (according to the console output). I am seeing occasional Warnings: 
"chan_iax2.c:5538 socket_read: Received mini frame before first full 
voice frame". When I let the call go all the way to voicemail to see if 
I can leave a message, it hangs up with the following:

Jun 28 18:59:30 WARNING[1133718208]: chan_iax2.c:5538 socket_read: 
Received mini frame before first full voice frame
  Jun 28 18:59:30 WARNING[1133718208]: chan_iax2.c:1396 
attempt_transmit: Max retries exceeded to host 65.29.4.223 on 
IAX2[iaxtel at 69.73.19.178:4569]/3 (type = 2, subclass = 2, ts=871, 
seqno=0)

     -- Hungup 'IAX2[69.73.19.178:4569]/2'

First- is this something I can expect to happen if I try to place a 
call to myself? Second could a couple of you with IAXTel accounts try 
to give my account a call and see if you get any different results? 
When you call, I have an "IVR" context set up which plays 3 sound files 
in a row ("Hello thank you for calling..."), then dials an extension 
for 15 seconds, then plays 2 more sound files ("I'm sorry, no one can 
answer...") and sends the call to voicemail. My number is 700-934-3568.

Or if anyone has any ideas for me to try/debugging to look at I'm all 
ears. I'm running the a recent CVS head (6/21). I'm not sure what else 
is relevant at the moment. I'd be happy to send sections of conf files 
or console traces if it would help.

TIA for any help!
