MoH for External Calls on CUCM 10

[Dmitry Golovenkin]

Hello,

We have a CUCM 10, which is configured to work with a CUBE and the external calls are made via a SIP trunk. The music on hold works fine for internal calls that are put on hold, however the external calls are only getting a beep when put on hold.

Any ideas?

Are you using unicast or multicast MoH? From the CUBE share debug ccsip when you place call on the hold along with sh call act vo br

[Dmitry Golovenkin]

Using unicast and the CUBE isn't set up an MTP or Transcoder. The codec used is G729. 

I will send the call logs shortly, once everyone leaves the offices to make it easier to log my own call.

Have you enabled g729 in IPVMS service parameters?

Hi, May I know your Router model for this setup ?

[Dmitry Golovenkin]

It's a Cisco 2921 router.

During the call I can see that it's using G729r8 codec:

Solved the problem by enabling G729 codec in the service parameters under MoH section.
