[Asterisk-Users] Cisco 7940 no audio

[Craig Waddington]

When we receive or make a call to the outside – they can hear us, but we cant hear them.   It may work 1 of 20 times. I have set canreinvite=no  and looked at many sites but cannot track down this problem.   Current setup:   Isdn Eicon Diva card / Capi -> Asterisk à network.   I have tried adjusting the RTP port in rtp.conf with the Cisco default ports, no luck.   Anyone had this problem, and has a fix?   Thanks.
