Set Up SIP Trunk Digest Authentication
The following procedure describes the tasks to configure digest authentication for SIP trunks.
Procedure
Step 1 |
Configure the SIP trunk security profiles; make sure that you check the Enable Digest Authentication check box. |
Step 2 |
Apply a SIP trunk security profile to the trunk. |
Step 3 |
Configure the enterprise parameter, Cluster ID, if not configured. This parameter supports Unified Communications Manager challenges to the identity of the SIP user agent that is sending a SIP request on the SIP trunk. |
Step 4 |
If Unified Communications Manager challenges the identity of SIP user agents that are sending SIP requests on the SIP trunk, configure the digest credentials for the application user in the Application User Configuration window. |
Step 5 |
If Unified Communications Manager responds to challenges from a trunk peer, configure the SIP realm. |
