scalar r/w Enumeration

Default DTMF Transport Method Configuration
          
Type of DTMF transport.
          
  * InBand: The DTMFs and voice are transmitted together in
    the RTP stream. Only reliable with G.711 or G.729 codecs.
  * OutOfBandUsingRtp: The DTMFs are transmitted as per
    RFC2833 if the peer supports it. Otherwise, DTMF transport
    falls back to Inband. This also applies when using SRTP.
  * OutOfBandUsingSignalingProtocol: The DTMF are transmitted
    as per the method set in the
    SipEp.InteropDtmfTransportMethod parameter.
      + With draft-choudhuri-sip-info-digit-00, the unit will
        negotiate rtpmap:111 X-nt-inforeq, and if the peer
        supports it, will send DTMF using SIP INFO and
        Content-Type: application/vnd.nortelnetworks.digits.
        Otherwise falls back to Inband.
      + With Info DTMF Relay, the unit will not advertise any
        method. When sending DTMF, it will mute the audio and
        send SIP INFO events with Content-Type application/
        dtmf-relay.
  * SignalingProtocolDependent: The signaling protocol has the
    control to select the DTMF transport mode. The behavior
    depends on the SipEp.InteropDtmfTransportMethod parameter.
      + With draft-choudhuri-sip-info-digit-00, the unit will
        advertise both RFC-2833 (RTP telephony events) and
        rtpmap:111 X-nt-inforeq and use one or both of these
        methods if the peer supports them, and fallback to
        Inband otherwise.
      + With Info DTMF Relay, the unit will not advertise any
        method. When sending DTMF, it will mute the audio and
        send SIP INFO events with Content-Type application/
        dtmf-relay.
          
If a specific value is set for the
EpSpecificDtmfTransport.Method parameter and the
EpSpecificDtmfTransport.EnableConfig parameter is set to
'Enable', then the specific value will override the current
default value.
