Nano CUBE - INFO DTMF Relay

The INFO dual-tone multi-frequency (DTMF) relay feature in Nano CUBE provides support for INFO-INFO DTMF relay. This support will enable passing through INFO requests with single DTMF digit information in the Content Body (0- 9, *, #, a, b, c, d) to the peer.

Restrictions for INFO DTMF Relay

  • Only INFO-INFO is supported. Other interworking modes such as INFO-KPML and INFO-NOTIFY are not supported.

  • Only one digit can be sent per INFO message. If there are more then one digits in the “Signal=” line from the incoming INFO, only the first digit is accepted.

Information About INFO DTMF Relay

The INFO DTMF relay feature is enabled on the NanoCUBE when both the inbound and outbound SIP dial peers are configured using DTMF-relay SIP-INFO configuration and negotiated end-to-end using the Allow and Accept headers.

When the NanoCUBE provisioned with SIP-INFO DTMF Relay option receives an INVITE/200 OK (for INVITE) with the Allow header containing INFO and Accept header containing “application/dtmf-relay”, it advertises its support for INFO DTMF relay using the Allow header and notifies the incoming call leg that INFO DTMF Relay has been negotiated by forwarding the Accept header. If the remote endpoint does not advertise its support for INFO DTMF Relay, the DTMF negotiation proceeds with the consideration that INFO is not one of the supported methods, and another common method will be negotiated. If nothing else matches between the two legs, DTMF negotiation will fallback to in-band mode.

How to Configure INFO DTMF Relay

Configuring INFO-INFO DTMF Relay Passthrough

SUMMARY STEPS

    1.    enable

    2.    configure terminal

    3.    dial-peer voice tag voip

    4.    dtmf-relay sip-info

    5.    end


DETAILED STEPS
     Command or ActionPurpose
    Step 1 enable


    Example:
     Device> enable
     

    Enables privileged EXEC mode.

    • Enter your password if prompted.

     
    Step 2configure terminal


    Example:
    Device# configure terminal
     

    Enters global configuration mode.

     
    Step 3dial-peer voice tag voip


    Example:
    Device(config)# dial-peer voice 300 voip
     

    Enters dial peer voice configuration mode.

     
    Step 4dtmf-relay sip-info


    Example:
    Device(config-dial-peer)# dtmf-relay sip-info
     

    Configures the INFO-INFO DTMF relay passthrough (via SIP-INFO messages) on the inbound and outbound dial peer.

     
    Step 5end


    Example:
    Device(config-dial-peer)# end
     

    Returns to privileged EXEC mode.

      Nano CUBE (INFO DTMF Relay)

      15.3(3)M

      The INFO dual-tone multi-frequency (DTMF) relay feature in Nano CUBE provides support for INFO-INFO DTMF relay. This support will enable passing through INFO requests with single DTMF digit information in the Content Body (0- 9, *, #, a, b, c, d) to the peer.
