I made the installation of a PBX with Asterisk 11.17, Dahdi 2.10 and wanpipe Driver 7.0.
I have two PCI cards: A Rhino 8-Port R8FXX-EC with echo canceller on board and w400 GSM Sangoma card.
When both cards active simultaneously, the calls made through the card Rhino present echo. I have already applied and HWEC OSLEC but none I can fix this.
The strange thing is that if I disable the driver of the Sangoma card echo disappears but I can not make calls from mobile network.
Any idea how to fix it.
Thanks in advance.
