I have a receptionist that is unable to resume calls after transferring or placing the call on hold. The receptionist does not have a hard phone and is using Jabber 12.5. The CUCM version is 10.5.2.18900-15 and CUAC version is OPR. 10.5.2.2804.
The Jabber client is associated with the application user for CUAC and Allow Control of Device from CTI is checked on the phone configuration and Directory Number configuration. The receptionist end user account is also associated with teh CSF device she is using. She can receive calls, transfer, and make calls, but cannot resume calls. When attempting to resume calls, the call drops after a few (2) seconds. Cisco documentation states Jabber can be used with CUAC.
