Resolution
To convert an IP phone from Skinny (SCCP) protocol to Session Initiation Protocol (SIP) with Cisco CallManager running 5.0.x, perform this procedure:
- On the Cisco CallManager Admin page, go to Bulk Administration > Phones > Migrate Phones > SCCP to SIP.
- On this screen, enter a query in order to select the device(s) to upgrade.
- On the next screen, select a Phone Profile. Add one if one is not already present.
To add a Phone Profile, perform these steps:
- Go to Bulk Administration > Phones > Phone Templates.
- When the migrate job is submitted, go to Bulk Administration > Job Scheduler.
Note: Sometimes, the job must be activated. If the job remains in Pending state, activate the Bulk Provisioning Service under Serviceability > Service Activation.
- Go to System > Enterprise Parameters and change the Auto Registration Phone Protocol option to SIP.
- Restart the Cisco CallManager service.
The Cisco 7960 IP phone registers and upgrades to the SIP load at the conclusion of this procedure.
