I have a Digium TDM411p (one fxo and one fxs). On the fxs is an Siemens cordless. I also have a couple of Cisco 7960Gs that I have converted to SIP (firmware 3.7.5). The PC is a 933 with 512 mb. I am running fxotune for the TDM400. This is a 2.4 kernel and I am at Zaptel 1.2.7 and Asterisk 1.2.10
SIP to SIP good FXS to FXO good FXS to SIP good SIP to FXO ECHOooo I have been playing with the echocancel (now at 256 taps) and the echotraining (at 1400), echocancelwhenbridged is no. I have also switched to MARK2 ECHO CAN and added Aggressive suppressor. I would describe this echo as not quite good enough. Better than before 70 or 80 test calls, but I would like it a little better. How do I remove the last of the echo, or is it possible? Does anybody have clean SIP on a TDM400 Do I scrap the SIP phones? Is there a better echo cancel than Mark2? Kevin Vieyra [EMAIL PROTECTED]
