hi Guys

i have a strange Music on hols issue as following:

i have CM 4.1 configured with cisco ios 3800

this gateway is configured as srst gateway and has moh locally configured as folling

moh [fileanem]

multicast moh 239.1.1.17 port 16384 route 10.76.27.0 1.1.1.1


1.1.1.1 is loopback

10.76.72.0 voice vlan

the router dsse the intervaln routing and this is the router subinterface vlan

i put the interface ip as well like 10.76.72.1 the problem the same

this interface is the h323 interface and srst source as well

the comand ccm-manger music-on-hold entered

the issue is iam getting locally music on hold

but when i call from pstn or mobile i cant get it only silent

accordeing to cisco :

If the POTS caller on hold does not hear a sound, Cisco CallManager has successfully completed the multicast MOH handshaking with the Cisco SRST gateway, but the gateway is failing to pick up the locally generated multicast RTP stream.

Use the show ccm-manager music-on-hold command to investigate



what i have seen :

#show ccm-manager music-on-hold

Current active multicast sessions : 1

Multicast RTP port Packets Call Codec Incoming

Address number in/out id Interface

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

239.1.1.19 16384 0/0 1702 g729r8


the incomfing interface is null !!!

no packet in/out

and the codec g729

while i have it on ccm as g711for moh ??


any idea ?!?!

thanks in advance
