we have the following scenario with OCS integration:
MGCP GW --> CUCM 6.1 --> Mediation GW --> OCS Conference IVR
When i call from the PSTN to the OCS Conference IVR, it should be possible to send DTMF and interrupt the women speaking. But when i press some digits on my phone, the women is still talking.
I tried some settings in the SIP Trunk from Callmanager to Mediation GW and on the MGCP Gateway that can change DTMF.
I did with no sucess. I also checked the Media Termination Point Required in the Trunk.
I have no idea what to do next and why it is not working with the DTMF.
When i call from the PSTN on a Cisco IP Phone that is on the Callmanager, DTMF works well. I hear the DTMF tones.
I hope someone can help me with this issue.
I also have a trace file with a non working call to the IVR and pressing some DTMF. I upload this when needed.
Thanks a lot for help...
