I would start with changing the rxgain and txgain on the channels. The echo is probaby accoustic echo caused by your SIP phone. Attenuating the rx or tx on the trunks may mitigate this somewhat. What model of SIP phone do you have? Jim

Maybe someone out there can help me (I know, he’s here again with yet another question). I’m having echo problem. Well not me. But callers on the PSTN side. So here’s my setup: Caller at home -> ISDN trunk with DID -> Telco Switch -> SIP Trunk -> Asterisk/Trixbox -> SIP User (Me) So if I dial my DID that goes to my telco company (who has the DID coming in via an ISDN trunk to them). They then send it too my Asterisk box via SIP. There, the Asterisk box does its nice little prompts and determines that the call needs to go too my SIP phone so it sends it. Now, when I get the call on my SIP phone, all is well. The caller on the PSTN side however has no end of problems with echo. I’ve read quite a few things on the net but it’s either Zapata this or FXO that. Where to start and how to fix? Andy Jaikissoon -- No virus found in this incoming message.
