Mediant 3000
Parameter Description
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
[IpProfile_SBCKeepUserAgent
Header]
Enables interworking SIP User-Agent headers between SIP
entities. The parameter defines the device's handling of User-Agent
headers for response/request 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 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.
Handle X-Detect
[IpProfile_SBCHandleXDetect]
Enables the detection and notification of events (AMD, CPT, and
fax), using the X-Detect SIP header.
 [0] No (default)
 [1] Yes
For more information, see Event Detection and Notification using
X-Detect Header on page 216.
SBC Media Tab
Transcoding Mode
[IpProfile_TranscodingMode]
Defines the transcoding mode (media negotiation) for the SIP entity
associated with the IP Profile.
 [0] Only if Required = (Default) Transcoding is done only when
necessary. Many of the media settings (such as gain control)
are not implemented on the voice stream. The device forwards
RTP packets transparently (RTP-to-RTP), without processing
them.
 [1] Force = Transcoding is always done on the outgoing leg.
The device interworks the media for the SIP entity (as both legs
