Command Reference

The principal advantage of the dtmf-relaycommand is that it transmits DTMF tones with greater fidelity than is possible in-band for most low-bandwidth CODECs, such as G.729 and G.723. Without the use of DTMF relay, calls established with low-bandwidth CODECs may have trouble accessing automated DTMF-based systems, such as voice-mail, menu-based ACD systems, and automated banking systems.

Note The cisco-rtpoption of the dtmf-relaycommand is a proprietary Cisco implementation and only operates between two Cisco AS5800 universal access servers running Cisco IOS Release 12.0(2)XH, or between Cisco AS5800 universal access servers or Cisco 2600 or 3600 modular access routers running Cisco IOS Release 12.0(2)XH or later releases. Otherwise, the DTMF relay feature does not function, and the gateway sends DTMF tones in-band.

Examples

The following example configures DTMF relay with the cisco-rtpoption when sending DTMF tones to dial-peer 103:

5800# configure terminal

5800(config)# dial-peer voice 103 voip

5800(config-dial-peer)# dtmf-relaycisco-rtp5800(config-dial-peer)# end

5800#

The next example configures the gateway to send DTMF in-band (the default) when sending DTMF tones to dial-peer 103:

5800# configure terminal

5800(config)# dial-peer voice 103 voip

5800(config-dial-peer)# no dtmf-relay5800(config-dial-peer)# end
