Ironically, I switched to an ATA and all problems disappeared.
I will try both your suggestions out for the Soft Phone and advise in a few. I'm currently using a Altec Lansing Headset / Mic combo. Thanks.

Also to achieve better performance on this, go to Control Panel, Sounds and Audio Devices, Voice tab and click the advanced button under Voice playback, and choose either stereo headset or whatever hardware you have there.

While they are counting, unplug your microphone from the count of 4 to 7. If the echo goes away when the mic is unplugged, your echo is accoustic (meaning what they say is being picked up by your microphone). This is essentially feedback. The solution is to prevent the mic from picking up what is received, but this is not always easy to achieve. What sort of audio hardware are you using? The tx and rx gain are indeed in zapata.conf. I would reduce the rxgain first, but no more than -3dB at a time. Also, keep in mind that this will affect all calls, so you will not be the only user affected.

In regards to the RxGain and TxGain, I gather you mean the settings located in Zapata.conf? Andy Jaikissoon _____ From: Jim Van Meggelen [mailto:[EMAIL PROTECTED] Sent: Thursday, August 17, 2006 8:55 AM To: 'TAUG' Subject: RE: [on-asterisk] Echo Problems 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?

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.
