Software Echo Canceller for Sangoma E1/T1 Cards
Hi, I encountered echo when connecting FS both Alcatel S12 exchange and NEAX PABX (FS in the middle) using Sangoma A102 (w/o hw echo canceller) using R2 signalling on Wanpipe drivers - even if the call bridges the 2 E1 ports. I can't understand why since this is almost a pass-through connection (didn't add media_bypass=true on the dialplan). My option is to use Oslec but I have to switch to DAHDI-mode. Is there any other recommended echo canceller for Sangoma cards using Wanpipe? Tks, /Nandy
You should talk to Sangoma support about issues like this.
