Protocols and Endpoints

Which DTMF relay method, configured on a SIP dial-peer, ensures that Unified CM does not invoke a media resource for calls to UCCX IVRs?

  • A sdtmf-relay h245-signal
  • B dtmf-relay rtp-nte
  • C dtmf-relay sip-notify
  • D dtmf-relay sip-kpml
Explanation

dtmf-relay sip-notify sends DTMF out of band in SIP NOTIFY messages. Unified CM can convert those messages to JTAPI signaling for UCCX, so an MTP is not required or invoked for the call.
