Hi, I have a setup of Asterisk with TDM13B card (1FXS,3FXO ports) and acouple of Cisco 7960 IP phones on SIP. So far i have managed to get the internal SIP calls going through without a hitch and can get to call through to the analog lines (SIP --> ANALOG) without any echos. However whenever we receive an incoming call via the analog lines (ANALOG --> SIP), there is an echo for about 15-30 seconds and it fades off thereafter
Initially i had an echo on both calling and receiving until i enabled the echotraining=yes option and that seemed to have cleared the outgoing calls. I cant seem to establish where the problem is. Please see my zapata.conf file below. PS: I have tried various values i.e FXS_KS and FXS_LS, also the tx and rx values as well but none seem to be working. Any help will be highly appreciated.
