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.
