Keywords:
  1. On the SIP Signaling Group screen, set the following fields to y:
    1. Enabled Layer 3 Test
    2. Peer Detection Enabled
      STEP RESULT:
      Communication Manager automatically detects the peer server.
  2. If the peer server is not Session Manager, set the Peer Server field on the SIP Signaling Group screen to Session Manager.
    ADDITIONAL INFORMATION:
    If the peer server is Session Manager, Session Manager inserts a +av.sci parameter in the OPTIONS response. Based on the presence of the +av.sci parameter, Communication Manager identifies the peer server as secured. If the OPTIONS response from Session Manager does not contain the secured call indication, the SIP element considers the request as unsecured. The SIP element inserts or overwrites the Av-Secure-Indication header with the value unsecured in the message.
