Do you have reinvites enabled? Are you running this over a linksys four port SoHo router/switch or something?

We have Poycom 501 phones. Prior upgrading to PRI we were till date using 4 analog lines connected with TDM card from digium & no echo for pure SIP to SIP lines. Now I have TE212P which had onboard echo cancellor. I am trying make myself clear before I blame on any network. B'cos for sure we have a spegati of networks & no QoS. Also the intresting thing is if I call from one extension to other dialing the main line & then extension the call is crystal clear. but when dialing a direct extension its a hell of echo. -- Deepak Stephen Davies <[EMAIL PROTECTED]> wrote: On 09/06/07, Deepak Naidu wrote: > Ya, I have done that, below is zapata.conf.

If you are getting echo on pure SIP to SIP calls, there's no point in fiddling around with your zapta.conf. That file is for configuring chan_zap, which is used to talk to Zap/ channels. Your calls are SIP to SIP so the zap channel and your PRI aren't being used at all. SIP calls are "pure digital" 4 wire lines so no electrical (Hybrid) echo will be present. The phones should not generate echo. If they are, they are presumably nasty phones (what kind are they?) and you should get properly made phones.
