Test Lab consists of CUCM 6.1.1 (latest patches), CUPS 6.0.2 (latest patches). Everything works ok once you are logged in to a phone, you can control the phone.

Seems the CTIGW controls are not updating OCS via CUPS when OCS requests the new mac address to control.
Testing is not being done with shared lines so each phone has one extension that is unique.
Anyone else run into this problem? Maybe a cisco bug?
