Yes.
Enables interworking SIP in-dialog, Contact and Record-Route
headers between SIP entities. The parameter defines the
device's handling of in-dialog, Contact and Record-Route
headers for messages sent to the SIP entity associated with the
IP Profile.

[-1] According to Operation Mode = (Default) Depends on the
setting of the 'Operation Mode' parameter in the IP Group or
SRD table:

B2BUA: Device operates as if the parameter is set to
Replace Contact [0].

Call State-full Proxy: Device operates as if the parameter
is set to Add Routing Headers [1].

[0] Replace Contact = Device replaces the address in the
Contact header, received in incoming messages from the
other side, with its own address in the outgoing message sent
to the SIP entity.

[1] Add Routing Headers = Device adds a Record-Route
header for itself to outgoing messages (requests\responses)
sent to the SIP entity in dialog-setup transactions. The
Contact header remains unchanged.

[2] Transparent = Device doesn't change the Contact header
and doesn't add a Record-Route header for itself. Instead, it
relies on its' own inherent mechanism to remain in the route
of future requests in the dialog (for example, relying on the
way the endpoints are set up or on TLS as the transport
type).
Enables interworking SIP Via headers between SIP entities. The
parameter defines the device's handling of Via headers for
messages sent to the SIP entity associated with the IP Profile.

[-1] According to Operation Mode = Depends on the setting of
the 'Operation Mode' parameter in the IP Group table or SRD
table:

B2BUA: Device operates as if the parameter is set to
Disable [0].

Call State-full Proxy: Device operates as if the parameter
is set to Enable [1].

[0] Disable = Device removes all Via headers received in the
incoming SIP request from the other leg and adds a Via
header identifying only itself, in the outgoing message sent to
the SIP entity.

[1] Enable = Device retains the Via headers received in the
incoming SIP request and adds itself as the top-most listed
Via header in the outgoing message sent to the SIP entity.
Enables interworking SIP Record-Route headers between SIP
entities. The parameter defines the device's handling of Record-
Route headers for request/response messages sent to the the
SIP entity associated with the IP Profile.

[-1] According to Operation Mode = (Default) Depends on the
setting of the 'Operation Mode' in the IP Group or SRD table:

B2BUA: Device operates as if the parameter is set to
Disable [0].
