<br><font size=3>Hi Steve,<br>
<br>
We have multicast MoH running from a local branch router.<br>
<br>
How have you got it setup? <br>
<br>
We basically have a local file flash. A multicast address set to the same
as the CM but limited the CM to a certain amount of hops to stop it from
going across the WAN. We then add the phones to the MRG that contains
the MoH server fooling the phone in thinking it is talking back to the
CM when in fact it is talking to the router instead.<br>
<br>
Is that what you are after?<br>
<br>
Karen <br>

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</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
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.</font><font size=3>
<br>
</font><font size=2 face="sans-serif"><br>
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.</font><font size=3> <br>
