MOH on router

Peter Valdes · ‎07-31-2012

Hi,

We are currently running a HUB and SPOKE IP Telephony model for the 1st time.

CUCM 7.1.5 pub, sub and CUC located at Site A. Site B has a 2Mb dedicated link to Site A for voice traffic only such as phone registration and VOIP. No other traffic apart from telephony traverse through this link. Each site has its own Voice Gateway and we use H323 and ISDN E1. Phones on Site B gets its IP Address from the local router using option 150 (Site A CUCM IP).

Phones on Site B have been experiencing bad static MOH and I was wondering if theres a guide to load the MOH on the local router instead of CUCM on the remote Site A?

What format does the MOH file have to be on for this to work?

Are there any other solution apart from changing the region on the Site B device pool to G711 to fix MOH?

Thanks

HI

You can use router as MOH source and this will reduce WAN BW utilisation. Below link shows you the exact confi in details.

Hi,

I have made the changes and applied the settings on both CUCM and SITE B router (also running SRST CME).

CUCM is also configure with multicast MOH using port number increment multicast.

Added MOH Server to MRG

Added MRG to MRGL

Applied MRGL to both phones on Site B aswell as the Site B router.

SRST works perfect.

Heres my config on the Site B router:

During normal mode (Phones register to central CUCM) when internal calls between two phones are place on hold, its blank. During SRST mode, same type of calls, I hear beeps.

Any idea?

Aaron Harrison · ‎08-03-2012

Hi

Firstly when in normal mode:

If you hear silence, that means that CUCM has told the phone to listen to mcast MoH. You should be able to browse to the phone and look at the 'streams' to see what mcast address the phone is listening to.

The key thing is to ensure you have configured MoH on CUCM so that the correct audio stream and server are assigned to the phone - each stream has a different mcast address or port number, so if a different one is assigned the phone will be told to listen to 239.1.1.2 or 239.1.1.1 with a different port. The same applies for different codecs, e.g. g729 region will get a different address/port than the same audio source in a g711 region.

Regards

Aaron

Hi,

During on HOLD, codec is G711 but there is no tx rx between the two phones within the region.

Ive also check the phone webpage on streaming statistics and during on MOH, stream status is Active (phone that was place on hold) but nothing on multicast IP or Port.

Thanks

Hi again,

I have followed a few guides in Cisco and Google. Most require a loopback interface.

Also when I issue the command, this is what I get

Hi,

I'm still stuck.

From phone to phone on the same network, I hear the CUCM MOH different MOH file to what is currently loaded on the Site B router flash.

There are 2 MOH loaded on the server but only one is set to multicast. Same MOH loaded on the flash.
