Hi. I am new in this matter. I installed a Sangoma Card B600 (4fxo + 1 fxs) on Elastix 1.5.2-2. Everyhting seems ok with the harware detection however, when receiving a call there is no sound at all. By picking an extension and try to dial out nothing happens. By picking the phone using the fxs channel I can make a call to one extension however, no sound at all. I did create 4 trunks zap/dahdi for each channel as well as the outbound route so extensions can find the way out when using the trunk. I created an inbound route so I can define where the incomming calls goes. I really dont understand what I am missing here! I got a second sangoma card and the same happens. It has been two weeks now after installing an re-installing elastix without managing to fix this problem. Could you help me on this? Regards.
