[Freeswitch-users] Software Echo Canceller for Sangoma E1/T1 Cards

[Nandy Dagondon]

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
