Which DTMF relay method configured on a SIP dial-peer will ensure that a media resource is not invoked by Unified CM for calls to UCCX IVRs?
The correct answer is A. dtmf-relay slp-kpml. UCCX only supports out-of-band DTMF. This can be applied at the CUBE to avoid a media resource being needed to address as it can directly handle the DTMF relay from RTP-NTE to xml/ios/voice/cube_uccx/cube_uccx_interop_bestprac_guide.pdf
