5. For the IP-to-IP application, since the back-to-back user agent (B2BUA) mode is
based on full termination at each leg, some requests, headers and URI parameters
and message bodies are omitted or changed while traversing the device. Responses
to requests within a SIP dialog are always sent independently at each leg regardless of
the other leg’s response.
• The following SIP Methods are omitted by the IP-to-IP application:
♦ MESSAGE
♦ PUBLISH
♦ SUBSCRIBE
♦ NOTIFY
♦ Out-of-dialog REFER
♦ Any other proprietary Method
• The following SIP message components are omitted by the IP-to-IP application:
♦ Message body (other than SDP)
♦ Specific parameters in the SIP headers handled by the device (such as To,
From, P-Asserted, Diversion, Remote Party ID, and Contact)
♦ Specific parameters in the SDP – these parameters may affect the RTP flow
at each leg independently
