Parameter Description
Web: Session Expires Mode
CLI: sbc-session-expires-mode
[IpProfile_SBCSessionExpiresMode] Defines the required session expires mode for this SIP
entity.

[0] Transparent = (Default) The device does not interfere
with the session expires negotiation.

[1] Observer = If the SIP Session-Expires header is
present, the device does not interfere, but maintains an
independent timer for each leg to monitor the session. If
the session is not refreshed on time, the device
disconnects the call.

[2] Not Supported = The device does not allow a session
timer with this SIP entity.

[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.
Web: Remote Update Support
CLI: sbc-rmt-update-supp
[IpProfile_SBCRemoteUpdateSupport] Defines whether this SIP entity supports the SIP UPDATE
message.

[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.
Web: Remote re-INVITE
CLI: sbc-rmt-re-invite-supp
[IpProfile_SBCRemoteReinviteSuppor
t] 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.
Web: Remote Delayed Offer Support
CLI: sbc-rmt-delayed-offer
[IpProfile_SBCRemoteDelayedOfferS
upport] 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.
Note: For this parameter to function, you need to configure a
valid Extension Coders Group ID for IP Profiles that do not
support delayed offer.
Web: Remote REFER Behavior
CLI: sbc-rmt-refer-behavior
[IpProfile_SBCRemoteReferBehavior] Defines the device's handling of REFER requests for this
SIP entity.

[0] Regular = (Default) Refer-To header is unchanged
