[asterisk-users] Help needed - Can anyone please explain to me what is causing this - TDM2400P

[Naija Man]

Hello all.

I have two identically configured asterisk servers each with a TDM2422P
(with two S400M FXS modules and two X400M FXO modules).

*1 works perfectly and the sound quality is great. However, I am having
audio quality problem with *2 when making or receiving calls over the PSTN -
the sound gets cut off from the earpiece when I start to speak in the
microphone and then when I stop talking, I can hear the other party!! I do
not have any problems with SIP calls.

Also, if I connect a POTs line to Channel 5 - (WCTDM/0/4 FXSKS) and dial the
number, it just keeps ring and the ZAP channel does not answer the call, nor
does it even show up in the console. If I call out to the PSTN through ZAP
5, All other channels are working ok. I have tried to recompile zaptel but
that did not solve the problem. I even went as far as swapping the TDM2400P
cards in the two asterisk servers and the problem still persisted,
confirming that the digium card is not faulty.

I did not notice any conflicting IRQs either. I would really appreciate help
in solving this problem.

Thanks.
