I dear im facing a big issue here.
I have a CCME 7.1 running IOS c2900-universalk9-mz.SPA.150-1.M6.bin. This CCME is connected to PSTN using BRI interfaces for outbound and inbound public phone calls. The company also needs to make some calls to a SIP server ( a kind of IVR) over a sip trunk that is beyond the wan VSAT link.
When I make the call using some SCCP and SIP phones registered on the CCME, I can send DTMF to the IVR system but when the call comes from PSTN via BRI the call gets connected but i cant send DTMF to the IVR system.
On the first attempt neither phones (PSTN or internal) were able to call this IVR but I had to configure software MTP and the internal phones could call the IVR system over WAN VSAT link.
This is the configuration of the CCME. Check also the attachment
