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><br><div class="gmail_quote">On Wed, Dec 9, 2009 at 7:22 AM, <span dir="ltr"><<a href="mailto:steve.siltman@assurant.com">steve.siltman@assurant.com</a>></span> wrote:<br>

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

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

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