Under call manager fallback whats your config for multicast ? or are you doing 
multicast over the wan ?

I am having this issue, one of the branch router is not streaming multicast moh. 
I was told it was working and has stopped working (not sure though)...when the 
user is put on hold - there is silence and the output of sh ccm music-on-hold   
is as below:

sh ccm music
Current active multicast sessions : 1
 Multicast       RTP port   Packets       Call   Codec    Incoming
 Address         number     in/out        id              Interface
===================================================================
239.1.1.1         16384   0/0              77911 g711ulaw                   
<<<<< no interface and packets stay at 0


CUCM - checked multicast is enabled and MRGL is assigned to DP ..On the router 
max-dn command was missing under fallback...rest is configured properly..with 
multicast route and correct file name..if i try adding max-dn i get below error 
and i am not even able  to add max-dn 1....
%DIALPEER_DB-3-ADDPEER_MEM_THRESHOLD: Addition of dial-peers limited by 
available memory

sh ephone summ output shows - no MOH file...i have tried removing and re-adding 
fallback and also re uploading the MoH file....could the issue be due to max-dn 
not configured....??? or it could be two separate issues..? Router is 3845 and 
IOS is 12.3(11r)T2....Any  clue if any one came across this????

sh ephone summ 
hairpin_block:
Max 500, Registered 0, Unregistered 0, Deceased 0 High Water Mark 501, Sockets 0
ephone_send_packet process switched 0


Max Conferences 12 with 0 active (4 allowed)
Skinny Music On Hold Status
Active MOH clients 0 (max 830), Media Clients 0, B-ACD Clients 0
No MOH file loaded    <<<<<<<<<<< even thoug file is in flash and triple checked 
and reuploaded.....
