SIP Realm Configuration


When you configure digest authentication for SIP trunks, Cisco CallManager challenges the identity of the SIP user agent that connects to the trunk every time the trunk sends a SIP request to Cisco CallManager; the SIP user agent, in turn, can challenge the identity of Cisco CallManager. For Cisco CallManager to respond to the SIP user agent, you must configure the SIP realm for Cisco CallManager.

For information on how to configure SIP realm for Cisco CallManager, refer to the Cisco CallManager Security Guide.
