Parameters state—Enable or disable the SIP operations
Default enabled
Values enabled | disabled
operation-mode—Select the SIP operation mode
Default dialog
Values • disabled—SIP operation disabled
• stateless—Stateless proxy forwarding. SIP requests are forwarded
based on the Request-URI and local policy. No transaction, session or
dialog state is maintained. No media state is maintained, and session
descriptions in the SIP messages are not modified.
• transaction—Transaction stateful proxy mode. SIP requests are
forwarded based on the Request-URI and local policy. The Net-Net
SBC maintains transaction state in accordance with RFC 3261. No
session or dialog state is maintained. No media state is maintained,
and session descriptions in the SIP messages are not modified.
• session—Session stateful proxy mode. SIP requests are forwarded
based on the Request-URI and local policy. The Net-Net SBC
maintains transaction state in accordance with RFC 3261. The SD also
maintains session state information. A Record-Route header is
inserted in requests so that the Net-Net SBC will remain in the path.
No media state is maintained, and session descriptions in the SIP
messages are not modified.
• dialog—Dialog stateful B2BUA mode. The Net-Net SBC maintains full
transaction, session, and dialog state. If media management is
enabled, full media state is also maintained and the Net-Net SBC
modifies session descriptions in SIP messages to cause the media to
flow through the Net-Net SBC.
dialog-transparency—Enable or disable SIP dialog transparency service to prevent
the Net-Net SBC from generating a unique Call-ID and modifying dialog tags
