Hi Cristobal, Just a starting point in your debug: - enable multicasting only on a server not both; if you will have both you must configure different starting IP addresses on each server and this will not work in Moh from flash scenario; - 239.1.1.1 is for audio source 1, codec g711u; make sure you are using this one for MoH. If you have g729 between regions you should have there 239.1.1.3 and G729 enabled for MoH in service parameters; - also you can use "debug ephone moh" for debugging on router. - Also in SRST condition, ip phones will receive only beeps. PSTN phones will receive music.
Hope this helps, Cristian ________________________________ From: ccie_voice-boun...@onlinestudylist.com [mailto:ccie_voice-boun...@onlinestudylist.com] On Behalf Of Cristobal Priego Sent: Wednesday, June 10, 2009 11:54 PM To: ccie_voice@onlinestudylist.com Subject: [OSL | CCIE_Voice] Integrating Cisco CallManager and Cisco SRST to Use Cisco SRST As a Multicast MOH Resource Hello Experts, This is not related to a lab or a pod, sometimes i use my customer's networks to study I have centralized deployment, the cluster has 2 servers running CCM 7.x, the MOH Servers are enabled for multicast, the ip address and port are configured, the multicast increment is set to "Ip address" On the selected audio source field on the option 1 (which is the MOH file that we want to use) the hop count is set to 1 The MOH audio source has the box check for Allow multicasting. I created an MRG that include both serves and is enabled for Multicast, the MRGL has the Moh MRG. the MRGL is assigned to the phones and the remote gateway. the phones have the user/network audio source selected to option 1 the remote gateway has the wav file loaded in flash. the call-manager-fallback has the ccm-manager music-on-hold moh <audiofile.wav> multicast moh 239.1.1.1 port 16384 route <ip address of the sub interface dedicated for voice> If I put a call on hold on the remote branch, the phone is not playing the music from the local gateway. i get beeps either internal or external calls. what am i missing? If i place a call internally i get the beeps, however in RTMT i can see that a multicast request becomes active If i issue a show ccm-manager music-on-hold i don't see anything your help is greatly appreciated
