Re: [CUCM 9.x] No dial tone when calling in

On the trunk you can assigned a Media Resource Group list and in this list is a Media Resource Group that contains certain resources like Conference, MTP, MOH and ANN.  ANN=Annunciators.  MRGL can be assigned at the trunk level in this case or device pool.  My question has a MRGL been assigned to either place and if so does it contain the CUCM

Annunciators resources?

Re: [CUCM 9.x] No dial tone when calling in

Kevin,

Yes I have assigned it to the SIP trunk, but ANN_2 isn't assigned. I have attached some screenshots.

It's weird because if I set up a Hunt Group to ring the phones directly when calling from outside then the dial tone works but when it goes to a Directory Number which then diverts it to VoiceMail, then hunt group - I get none. Could it be that Unity Cx has something to do with this?

Re: [CUCM 9.x] No dial tone when calling in

How is connection integrated?  SIP or SCCP?

Re: [CUCM 9.x] No dial tone when calling in

Between CUCM and CUC it's SCCP.

So you get no ring back when transfering from Unity back to CUCM?

Make sure ANN_1 and ANN_2 is assigend to a MRG.  Make sure the MRG is assiged to a MRGL and it needs to be associated to both the SIP trunk coming inbound to the CUCM server as well as the VoicePorts configured for Unity Connection.  Generally assigning the MRGL to the device pool that is used for Voicemail will work.  This has to be done.

Hi Kelvin,

Sorry that did not help either. I can provide you with remote login if you wouldn't mind taking a look?

Re: [CUCM 9.x] No dial tone when calling in

It looks that way. Because if I ring a DDI or Hunt Group that does not go via CUC, I get a tone. If it goes to CUC and then back CUCM, then nothing.

[CUCM 9.x] No dial tone when calling in

Did you ever get a resolution to this problem? I have almost exactly the same setup as you and have the same issue.

[CUCM 9.x] No dial tone when calling in

Yes, Brian, I did. The problem was that my annuciater was not registered. Once that was enabled, everything started working!
