Keywords:
  • The call originator is SIP.
    If the call originator is not SIP, Communication Manager does not apply SIP Direct Media to the call.
  • The following fields in the SIP signaling group screen of the originating SIP User Agent (UA) is set to y:
    • Direct IP-IP Audio Connections
    • Initial IP-IP Direct Media
  • The call-originating party does not have a call on hold.
  • If Media Encryption Over IP is y on the system-parameters customer-options screen (page 4), set SDP Capability Negotiation for SRTP to y on the system-parameters features screen (page 19).
Note:
If you do not meet with the prerequisites for SIP Direct Media, Communication Manager allocates media processors and shuffles the call after the connection is established.
