Hi all, please help me with this MoH issue.
Problem: MoH will not play at the branch office. Callers from across the PSTN get the silent treatment during hold.
Central site:
- CUCM cluster v7.1
- MoH Server is using 239.2.1.1 / port 16384 with "increment multi-cast" on IP Address
- Audio source No.2 has file name of "SampleAudioSource" with Max Hop = 2
run sql select mohaudiosourceid, multicastaddress, multicastport from mohservermulticastinfo where mohaudiosourceid='2'
mohaudiosourceid multicastaddress multicastport
================ ================ =============
2 239.2.1.5 16384
2 239.2.1.6 16384
2 239.2.1.7 16384
2 239.2.1.8 16384
Branch office:
- Cisco 2921 router running MGCP
- IP phones are in a Common Device Configuration with Audio Source set to "2-SampleAudioSource"
- Router flash has SampleAudioSource.au
- ip multicast-routing is enabled
- call-manager-fallback configured with:
ip source-address 10.118.28.1 port 2000
moh "SampleAudioSource.au"
multicast moh 239.2.1.5 port 16384 route 168.65.253.122 10.118.28.1
- Loopback address configured with:
interface Loopback0
ip address 168.65.253.122 255.255.255.255
ip pim sparse-mode
When I place a call on hold from the branch, this is the "show ccm music-on-hold" output:
Current active multicast sessions : 1
Multicast RTP port Packets Call Codec Incoming
Address number in/out id Interface
===================================================================
239.2.1.5 16384 0/0 3644 g711ulaw
This is the show ip mroute output:
(*, 239.2.1.5), 00:03:35/00:02:14, RP 168.65.251.1, flags: SJCL
Incoming interface: Null, RPF nbr 0.0.0.0
Outgoing interface list:
GigabitEthernet0/0.300, Forward/Sparse, 00:03:35/00:02:08
What am I missing that is causing the MoH to not come across?
