Cisco 7965 SCCP
Please check the following on the phone you're going to control:
-Allow Control of Device from CTI (on the device and the line) and End User association with the device.
-Check that the Owner User ID is set to the Jabber user you want.
-Go to Application > Cisco Jabber:
- Check that the user is part of a CTI Gateway Profile
- Then go to CCMCIP Profiles ( if there's none you'll have to create it ) and see that there's the end user as well.
If you've checked everything above the recommendation will be to restart the CTI Manager service on the CUCM server that the that should restablish connection
Note: Of course connectivity to the CUCM Server from the PC in question should be confirmed to use this feature, that's a basic thing you might want to check.
