User's Manual 23. Coders and Profiles
Parameter Description

[3] Supported = The device enables the session timer with
this SIP entity. If the incoming SIP message does not include
any session timers, the device adds the session timer
information to the sent message. You can configure the value
of the Session-Expires and Min-SE headers, using the
SBCSessionExpires and SBCMinSE parameters,
respectively.
Remote Update Support
sbc-rmt-update-supp
[IpProfile_SBCRemoteUpdateSu
pport]
Defines whether the SIP UPDATE message is supported by the
SIP entity associated with the IP Profile.

[0] Not Supported = UPDATE message is not supported.

[1] Supported Only After Connect = UPDATE message is
supported only after the call is connected.

[2] Supported = (Default) UPDATE message is supported
during call setup and after call establishment.
Remote re-INVITE
sbc-rmt-re-invite-supp
[IpProfile_SBCRemoteReinviteS
upport]
Defines whether the destination UA of the re-INVITE request
supports re-INVITE messages and if so, whether it supports re-
INVITE with or without SDP.

[0] Not Supported = re-INVITE is not supported and the
device does not forward re-INVITE requests. The device
sends a SIP response to the re-INVITE request, which can
either be a success or a failure, depending on whether the
device can bridge the media between the endpoints.

[1] Supported only with SDP = re-INVITE is supported, but
only with SDP. If the incoming re-INVITE arrives without SDP,
the device creates an SDP and adds it to the outgoing re-
INVITE.

[2] Supported = (Default) re-INVITE is supported with or
without SDP.
Remote Delayed Offer Support
sbc-rmt-delayed-offer
[IpProfile_SBCRemoteDelayedOf
ferSupport]
Defines whether the remote endpoint supports delayed offer (i.e.,
initial INVITEs without an SDP offer).

[0] Not Supported = Initial INVITE requests without SDP are
not supported.

[1] Supported = (Default) Initial INVITE requests without SDP
are supported.
Remote Representation Mode
sbc-rmt-rprsntation
[IpProfile_SBCRemoteRepresent
ationMode]
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
SRDs 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
