I am trying to setup an Ad-Hoc conference with CISCO CUCM 12.0 using a third party SIP Phone as a host. I have already setup the 3-party conference using Jabber Client as a host. I have found by looking at the traffic from Jabber Client that it sends out a REFER with
Content-Type: application/x-cisco-remotecc-request+xml\r\n
when I press the green button next to 'waiting to Join' and the CUCM manages the conference internally by reusing the existing dialog and don't reveal the conference factory URI to the client.
But, with the third party application, when I am sending an Invite to the server with "IMS Conference Factory URI" as the Request-URI, I am getting 404 NOT FOUND response.

Is there anything else that I need to configure in CUCM or is there some sequence of events that needs to be followed while setting up the conference?
