I am surprised that you are getting echo on SIP calls. You can get echo in two scenarios on SIP calls.
1. If SIP calls are crossing to PSTN (inbound/outbound). Here you need to enable echo canceller and AGGRESSIVE if needed in zconfig.h. 2. Second source of echo on SIP calls could be ACOUSTIC. The phone sets you are using may not handle this well. In my experience sound quality deteriorates if there is network trouble or congestion on SIP calls I hope this helps.
