Hi Michael, You're welcome. You will need this command:
multicast moh 239.1.1.x port 16384 route VOICE_VLAN_IP LOOPBACK_IP Basically, when you configure this, the router will start to transmit music to multicast ip address 239.1.1.x port 16384 on interfaces VOICE_VLAN and LOOPBACK. Loopback is needed there because you will need MoH for the PSTN phones. After that you must configure phones to "listen" to that address from call-manager-fallback(239.1.1.x, where x depends on codec used). When a phone is on hold it will listen to the address from it's configuration file. You can verify what address CCM configured for the phones by verifying configuration files on TFTP Server. Also, if you did a mistake in "multicast moh" command you must delete it and put it again in order to work with the new configurations.

I did verify multicast routing is not needed on any router. (Thanks Cristi). Also no PIM is needed. I DID have to reboot the router becasue the multicast packets kept coming from the loopback interface on my last configuration even though SRST source-address was voice VLAN interface. Seemed to need the route command in my last configuration. IP of loopback AND IP of voice VLAN. I think MGCP was bound to loopback and SRST was bound to voice vlan. I'll re-try Christ's route meaning, but think if I didn't also have loopback music stopped. Never configured the route command for a customer. Still working on perfecting the configuration and meanings of everything. I can get it to work, but that's not expert enough for me. ________________________________________ From: Azeem ahamed [azeemo...@gmail.com] Sent: Thursday, June 11, 2009 4:10 AM To: Michael Ciarfello Cc: Cristobal Priego; ccie_voice@onlinestudylist.com Subject: Re: [OSL | CCIE_Voice] Integrating Cisco CallManager and Cisco SRST to Use Cisco SRST As a Multicast MOH Resource Also do try putting in the ip pim sparse mode when you enable the Multicasting On Thu, Jun 11, 2009 at 7:30 AM, Michael Ciarfello<mciarfe...@iplogic.com> wrote: > Hi and welcome. > > Did you upload the MOH file to all the other servers in the cluster? > Multicast routing enabled on the remote gateway? > You have 239.1.1.1 which implies FIRST music source, G.711.
