Multicast moh on SRST router

VON CLAWSON · ‎09-25-2007

I am having a problem with this configuration. All seems to be configured correctly now but I still cannot hear the moh. Here is the configuration:

call-manager-fallback

max-conferences 8 gain -6

ip source-address 172.26.3.1 port 2000

max-ephones 48

max-dn 100 dual-line preference 2

moh Muzak_MOH_688808.ULAW.wav

multicast moh 239.2.1.1 port 16440 route 172.26.3.1 172.31.3.1

I have verified that the file is good and can be played. Here is the output of sh ccm music:

OCH903#sh ccm music

Current active multicast sessions : 1

Multicast RTP port Packets Call Codec Incoming

Address number in/out id Interface

===================================================================

239.2.1.1 16440 153/153 967 g711ulaw Lo0

OCH903#sh ccm music

Current active multicast sessions : 1

Multicast RTP port Packets Call Codec Incoming

Address number in/out id Interface

===================================================================

239.2.1.1 16440 365/365 967 g711ulaw Lo0

OCH903#sh ccm music

Current active multicast sessions : 1

Multicast RTP port Packets Call Codec Incoming

Address number in/out id Interface

===================================================================

239.2.1.1 16440 569/569 967 g711ulaw Lo0

So the packets are going in and out and are incrementing.

Any idea what could be wrong?

You could try either:

1 - Bouncing the router, or

2 - Do a no ccm-manager music-on-hold

and under telephony-service delete

moh Muzak_MOH_688808.ULAW.wav

multicast moh 239.2.1.1 port 16440 route 172.26.3.1 172.31.3.1. Then re-enter all of the above again.

Also make sure you have

a. One music on hold source defined in Callmanager.

b. Codec used between MOH server and the remote region is g711 and not g729.

Note that this streaming works only when wan connection is up and phones are registered to Callmanager.

Hey thisisshanky,

I have already created a moh region and DP. And the moh server is in that DP. Codec always comes up as g711 in the sh ccm music.

I'll try this. Thanks
