dtmf-relay

Release 12.0(7)XK

Note The cisco-rtp version of dtmf-relay is a proprietary Cisco implementation and only

interoperates between Cisco AS5300 universal access servers, Cisco 2600 or 3600 modular access

routers, or Cisco MC3810 concentrators running Cisco IOS Release 12.0(7)XK, or later releases.

Otherwise, the DTMF relay feature will not function and the gateway will send DTMF tonesinband.

Note Theh245-alphanumeric and h245-signal DTMF settings onanMC310 concentrator require

a high-performance compression module (HCM) and are not supported on an MC3810 concentrator

with a non-HCM voice compression module (VCM).

Example

The following are two examples of the dtmf-relay command:

• Conﬁguring with dtmf-relay cisco-rtp or h245-signal when sending to dial-peer 103. Enter the

conﬁguration commands, one per line.

Router# configure terminal

Router(config)# dial-peer voice 103 voip

Router(config-dial-peer)# dtmf-relay cisco-rtp h245-signal

Router(config-dial-peer)# end
