[cisco-voip] Fw: Multicast SRST, branch router, no moh for PSTN caller

[CarlosOrtiz at bayviewfinancial.com]

Is the music on hold file a custom file you created that does not exist on 
the Call Mgr?  I ask this to verify that you are definitely getting the 
music from the router's flash between the IP phones. 

When you put a PSTN caller on hold run this command :  show ccm-manager 
music-on-hold

You should see output similar to the follwoing:

Current active multicast sessions : 1
Multicast       RTP port        Packets         Call    Codec Incoming
Address         number  in/out          id                      Interface
===================================================================
239.1.1.1       16384           326/326         42      G.711ulaw Lo0 *

This will tell you the multicast address being sent from flash and the 
codec.

It might be that your gateway does not have the correct Media Resource 
Group List.  In the case of the PSTN caller your MOH RTP stream is between 
the Gateway and the phone.  Post you findings and I may be able to help 
you find the issue.

Hi there,

I have installed an 3825 Router in a branch office, to avoid multicast 
crossing the WAN links. I have configured, as mentioned in the cisco 
documents, the moh on the branch router. That works fine for the phones, 
but if an external caller is put on hold, he hears nothing. Is it 
possible, that i need a stream for ulaw and alaw? I think,I have 
configured the ulaw stream. The router is in france, so I think, they 
would need alaw.

Or has anyone of you had this problem before?

Any response would be helpful, many thanks
