[asterisk-users] No audio on Sangoma A104.

[Alex Balashov]

Hi all,

I am having a very strange problem.  I am terminating a PRI (5ESS switch 
type, national plan, 23B+1D (24)) into a Sangoma A104 and am not able to 
produce any audio heard on the PSTN end of the call.

Not sure what's wrong - the card worked before under a Trixbox setup.

I'm running kernel 2.6.19 (tried 2.6.24.3 but had to downgrade as 
wanpipe stuff would not compile), zaptel 1.4.9.2, and wanpipe 3.3.2.

If anyone has any ideas, please let me know!  There is no audio, but a 
very faint stutter of echo (not audio) on the far end in correspondence 
with playback of various audio files, etc.

I've tried messing with the T1 line build-out settings and txgain out of 
the belief that perhaps the way the circuit is broken out is not 
particularly favourable (it runs between floors of a building and is 
wired from Cat-5e - don't ask, I didn't do it), but there are no errors 
on the T1 level and we've got several other PRIs designed the same way 
running into Cisco AS5300s without a problem.

Thanks!
