We have a call manager express system and we talk with outside via our service provider. We send and receive calls with H323 protocol and g729r8 codec. If I route incoming calls to an extension there is no problem they can talk but when I route the incoming call to IVR (which is in the cue module) we cant hear IVR call is dropping. I think it is because of that we send calls to cue via sip and g711. How can we make a them talk with each other? I tried
voice service voip
allow-connections h323 to sip
allow-connections sip to h323
allow-connections sip to sip
these config but it didnt help. Any suggestions?
