Hi,


I have to configure DTMF in dial peer voip but I don't know which type have to configure rtp-nte or cisco-rtp.


What's the difference both them?

Thank you.

It will depend on your setup-

For CCM we use dtmf-relay h245-alphanumeric

since CCM only understand this type of DTMF as inbound.


For SIP we use Named Telephony Events (NTE), or RFC 2833 which is dtmf-relay rtp-nte


The cisco-rtp Forwards DTMF tones by using Real-Time Transport Protocol (RTP) with a Cisco proprietary payload type.

Hi,


thank you for your answer but I forget to tell you that I'm using CCME on Cisco 1760-V.


Is there difference with CCM configuration?
