CHAPTER19 Coders and Profiles
Mediant 4000 SBC | User's Manual
Parameter Description
✔ 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 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.
'Keep User-Agent Header'
sbc-keep-user-agent
[IpProfile_
SBCKeepUserAgentHeader]

SIP entities. The parameter defines the device's handling
of User-Agent headers for response/request messages

Depends on the setting of the 'Operation Mode'
parameter in the IP Group or SRDs table:
✔ B2BUA: Device operates as if this parameter is set
to Disable [0].
✔ Call State-full Proxy: Device operates as if this
parameter is set to Enable [1].
■ [0] Disable = Device removes the User-Agent/Server
headers received in the incoming message from the
other side, and adds its' own User-Agent header in the
outgoing message sent to the SIP entity.
■ [1] Enable = Device retains the User-Agent/Server
headers received in the incoming message and sends
the headers as is in the outgoing message to the SIP
entity.
