Hello all. <br><br>I have two identically configured asterisk servers each with a TDM2422P (with two S400M FXS modules and two X400M FXO modules).<br><br>*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.<br><br>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.
<br><br>I did not notice any conflicting IRQs either. I would really appreciate help in solving this problem.<br><br><br>Asterisk1:<br>centOS 4.3<br>asterisk 1.2.8<br>zaptel 1.2.6<br><br>Asterisk2:<br>CentOS 4.4<br>Asterisk
