Has anyone or can anyone point me to links regarding Out of Band DTMF?
Our current setup is:
ISDN -> Voice Gateway -> H323 -> CUCM
The goal is when customers calling in via ISDN enter digits, the DTMF must be transparent from our CUCM and the agent.
Thanks for the reply.
I need the DTMF tone to be silent. I read OOB DTMF may be the solution.
No need to secure the packet or logs or encrypting connection between VG and CUCM.
Let me know if you have suggested links?
I found some but they are SIP trunks. Right now, we have PRI to VG H323 to CUCM
