trunk-to-ip channels

This command configures the Trunk-to-IP Channels table, which lets you route multicast voice traffic over T1/E1 (i.e., mapping between T1/E1 channel and multicast group). The source and destination of the traffic are multicast groups.

Example

This example configures multicasting:

■

For the receiving MSBR (traffic from multicast group is forwarded to channel of the E1):

(config-voip)# trunk-to-ip channels 0
(channels-0)# trunk-id 4
(channels-0)# b-channel 1
(channels-0)# local-ip-address 239.5.1.2
(channels-0)# local-udp-port 10000
(channels-0)# rtp-direction RTPRxOnly
(channels-0)# activate

■

For the sending MSBR (traffic from channel of the E1 is forwarded to multicast group):

(config-voip)# trunk-to-ip channels 0
(channels-0)# trunk-id 4
(channels-0)# b-channel 1
(channels-0)# remote-ip-address 239.0.1.2
(channels-0)# remote-udp-port 20000
(channels-0)# rtp-direction RTPTxOnly
(channels-0)# activate
