This is critical and I just resolved a similar problem. A call control group was not properly configured on Node 2 only Node 1 ports where setup. There are 2 possible methods. Remember, make sure your RMCMuser account a password are working. These CTI ports are created on CUCM via UCCX and should be deleted from UCCX when changing or rearranging. Step 1. Take a snapshot of the CALL CONTROL group so you can recreate it faster. Delete the group in UCCX. Step 2. On CUCM PUB, look for DEVICE PHONES associated to port numbers allocated IPPCq_12XX. etc.. DELETE these associated numbers. Step 3. On CUCM PUB check CALL ROUTING, ROUTe Plan Report, UNASSIGNED DN's. look for same DN's associated to CTI 12XX. ect.. DELETE. btw,, you should clean up the UNassigned DN's in general maintenance too!. STEP 4. On UCCX rebuild your CALL CONTROL group. IF that does not work then repeat all the same steps. On UCCX stop Services, NODE MANAGER, both if HA. Then on CUCM PUB, SERVICEABILITY, Control Center - Feature Services, CM Services, SELECT Cisco CTIManager , RESTART button below. Then START UCCX PRI NODE MANAGER, then UCCX SEC. Node Manger. On UCCX PUB,, rebuild CALL CONTROL GROUP... should fix.
