Play MoH from Router at Remote Site without enabling SRST

Hi

Is it possible to play MoH from router at remote site, without acutally configuring the SRST feature on the router (say Cisco 2811).

Thanks.

I may be mistaken here but I believe you still need  to configure the "call-manager-fallback" stanza to get to the moh commands on the router.  Multicast is also required in this scenario because, basically, the cisco approach is a workaround.  You are tricking devices into listening to a multicast address that you are "containing" to a remote site LAN topology.  Thus all remote site devices use the same multicast address.

At least, this is my understanding for what thats worth.

Re: Play MoH from Router at Remote Site without enabling SRST

yes William is correct.

You will need these commands even though you don't want SRST

call-manager-fallback

moh music-on-hold.au

multicast moh 239.1.1.1 port 16384 route X.X.X.X

ip source address X.X.X.X port 2000 (maybe not needed)

& also

ccm music-on-hold

Thank you for help !

Re: Play MoH from Router at Remote Site without enabling SRST

The multicast stream does not necessarily have to come from the router.

You could use a PC at the remote site to multicast MoH using a program such as VLC.

Re: Play MoH from Router at Remote Site without enabling SRST

Have you gotten VLC to work as the MOH server?  It sounds bad everytime I try it.  I've downloaded the G711u file from the CUCM MOH server and multicasting that without any transcoding.  Just sounds bad.  Have you had any luck?

Couple of notes....

In addition to CLI mentioned, you'd also need to add max-ephone and max-dn (under call-manger-fallback)

Just set those to  1 for MoH sub-system to initialize properly.

Also needed is a loopback interface for MMoH. Not necessarily a routeable one; Any IP (bogus too)

with a /32 mask will suffice too.

Haven't played with VLC but have used WMP to test live MoH feed. You need to play with input gain on

the port and impedence settings to get an acceptable audio quality.

Hope this helps...
