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
multicast moh 18.104.22.168 port 16384 route 10.76.27.0 22.214.171.124
126.96.36.199 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
188.8.131.52 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
