It is the responsibility of your device (SJpnone, mic/speaker & pc) to handle it's half of the echo problem (prevent what is playing in the speaker from being picked up in the microphone.
I played with sjphone months ago with mic & speakers and experienced the same trouble. I would expect it to work much much better with headphones instead of pc speakers (the test licence expired before I could check this out). > Are there any parameters I can use in the sip.conf > or anywhere else to reduce the echo?? > > When making a PSTN call from the phone on the S100U > there is no echo at all.. ( I have echocancel=yes > and echocancelwhenbridged=yes in zapata.conf ) You are handling the asterisk end here. In fact echocancelwhenbridged=no should be fine as well. If you are connecting sip calls to telco or pbx it may be beneficial to uncomment KFLAGS+=-DAGGRESSIVE_SUPPRESSOR in the zaptel Makefile then make install.
