Parameter Description
sbc-keep-routing-headers
[IpProfile_SBCKeepRouting
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 SRDs table:


to Enable [1].
 [0] Disable = Device removes the Record-Route headers received
in requests and responses from the other side, in the outgoing SIP
message sent to the SIP entity. The device creates a route set for
that side of the dialog based on these headers, but doesn't send
them to the SIP entity.
 [1] Enable = Device retains the incoming Record-Route headers
received in requests and non-failure responses from the other side,
in the following scenarios:

The message is part of a SIP dialog-setup transaction.

The messages in the setup and previous transaction didn't
include the Record-Route header, and therefore hadn't set the
route set.
Note: Record-Routes are kept only for SIP INVITE, UPDATE,
SUBSCRIBE and REFER messages.

table:

B2BUA: Device operates as if this parameter is set to Disable

SIP entity.
 [1] Enable = Device retains the User-Agent/Server headers
