[cisco-voip] Native Call Queuing on UCM 12.5 with SIP Trunks

Additionally, If it’s a custom MoH (not the built in Cisco tune), make sure the file is uploaded to each CUCM server individually; the working phone 2 phone scenario could be happening on nodes where the moh file is, and the trunk registered to a node where it is not.

Thanks,

Ryan

Hi,

Try to check if your trunk has access to moh resources.

This means your trunk needs to be placed inside a device pool whose mrgl contains at least one mrg containing at least one moh server.

Sip trunk > device pool > mrgl > mrg > moh server.

Additional test: call some external party through your sip trunk and try to put called party on hold. Does the called party hear moh?

Regards

Sorry forgot to mention that Supplementary services such as call forward all, transfer, hold/retrieve, and conferencing work fine.

Hi all,

This being back on the tools is doing my head in. I think I’ve been away too long.

So I have configured native call queuing on UCM 12.5.x
Internal calls queue fine. The initial announcement plays. Period announcements work and the MOH is fine in between.

External calls hear the initial announcement.
There is no MOH after the announcement and the external user has ring-back tone.
There is no periodic announcement.

Any thoughts on why internal is okay and external is not working? Is it relating to SIP supplementary services?

Cheers
Dana
