MOH : Unique audio sources limitation

[francois.eyraud]

Hello,

We have a CUCM V7 with more than 100 distant sites (GW 28xx) and we need one distinct on hold message per site.

But the number of unique audio source per cluster cannot exceed 51.

Is there a way to extend the number of unique audio sources permitted ?

If you're using MoH from the local router's flash at each site, CUCM can be setup with just one audio source for all sites since the file being played will come from the local gateway not CUCM.  All CUCM will do is instruct the phones to listen to a certain multicast IP/port number which will be streaming a unique audio file at each site from the gateway on that particular IP/port.

Here's how this is setup:
