Autoregistration with Multiple Protocol Support
Autoregistration means that unknown phones will be coming into the network. Because the phones are unknown, Cisco Unified Communications Manager does not know whether the new phones should be registered as phones that are running SIP or as phones that are running SCCP; therefore, the system administrator uses Cisco Unified Communications Manager Administration to specify the default protocol that new phones should use for autoregistration.
Cisco devices that support both SIP and SCCP (Cisco Unified IP Phone 7905, 7911, 7912, 7940, 7941, 7960, 7961, 7970, and 7971) will auto register with the protocol that is specified in the Auto Registration Phone Protocol Enterprise Parameter. Cisco devices that only support a single protocol will auto register with that protocol regardless of the Auto Registration Phone Protocol setting. For example, the Cisco Unified IP Phone 7902 only supports SCCP. If a Cisco Unified IP Phone 7902 auto registers, it will use the SCCP regardless of whether the Auto Registration Phone Protocol is set to SIP.
 Note |
To ensure that autoregistration works correctly, ensure the Device Defaults Configuration window specifies the correct phone image names for SIP and SCCP. |
To deploy phones in a mixed-protocol environment, you must perform additional steps when autoregistering a new mixed batch of phones. The first step requires that the administrator set the Cisco Unified Communications Manager Auto Registration Phone Protocol parameter in the Enterprise Parameters Configuration window to SCCP and install all the phones that are running SCCP. The second step requires that the administrator change the Auto Registration Phone Protocol parameter to SIP and autoregister all the phones that are running SIP.
