Hi, i have the following voice path:
digital phone - Nortel IP trunk - WAN - CCM - ip phone
digital phone - Nortel IP trunk - WAN - IPCC(IVR) - ip phone (agent)
The Nortel IP Trunks uses g.729a for communition trough the WAN. Also i have in my network CCM 4.1 and IPCCX 4.0 using g.729 codec.
My problem is that when we receive a call from the Nortel to another phone the call can stablish but when the Nortel send the call to the IVR the call drops on the first prompt.
Any help, thanks
