Tips |
| • The | |||
|
|
|
| corresponding voice port. | |
|
|
|
| • The session protocol multicast command is essential for voice multicasting. | |
|
|
|
| • The session target for voice multicasting dial peers is a multicast address in the range of from | |
|
|
|
| 224.0.1.0 to 239.255.255.255. This session target must be the same for all routers in a session. The | |
|
|
|
| audio RTP port is an even number in the range of from 16384 to 32767 and must also be the same | |
|
|
|
| for all routers in a session. An | |
|
|
|
| traffic for that session. | |
|
|
|
| • The following codec restrictions apply: | |
|
|
|
| – You must configure the same codec on all dial peers and routers in a session. | |
|
|
|
| – Only G.711, G.726, and G.729 codecs are supported. | |
|
|
|
| – When the default codec, G.729r8, is used, it does not appear in the configuration. | |
|
|
|
| • Voice activity detection is enabled by default. Cisco recommends that this setting should not be | |
|
|
|
| changed. | |
Ethernet Configuration
Configure the router’s Ethernet interface as follows:
!Configure physical interface for transmitting multicast packets.
!
interface ethernet 0/0
ip address 1.5.13.13 255.255.255.0 ip pim
Voice Multicasting over a WAN
The configuration for voice multicasting sessions over IP on Frame Relay is the same as for the Ethernet LAN in the previous example. Configure the WAN interface on each router with the ip address and ip pim commands and the
