[cisco-voip] MOH from Router Flash between internal callers

[steve.siltman at assurant.com]

Has anyone been able to get this too work?  I turned on Multicast within 
the internal network at this remote site and I'm unable to get the phones 
to hear the MOH between two internal Cisco IP Phones.  Years ago, I read 
that this wasn't possible but was hoping this was resolved in later 
versions.  We are running v7 Call Manager with 12.4.24 router code.  MOH 
works fine to external customers.  It seems fairly straight forward as the 
one Cisco IP phone issues the Hold and sends the multicast ip address to 
the other phone.  I'm not sure why the other phone doesn't pick up on the 
stream.  Grr

If this isn't supported then I'll have to allow MOH across the WAN and 
forget about using the routers flash outside of SRST.

I've got a ticket open with Cisco and they verified the configuration and 
have asked for trace files.  Either this TAC person doesn't know it isn't 
supported or something has changed since my Cisco Voice Gateways book was 
printed in 2006.

Thanks,

-Steve
