User's Manual
Determines the required session expires mode of the IP 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 IP entity.

[3] Supported = The device enables the session timer with
this IP 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.
Defines whether the destination UA sends RTP immediately
after it sends 18x response.

[0] Immediate = (Default) Remote client sends RTP
immediately after it sends 18x response with early media.
Device forwards 18x and RTP as is.

[1] Delayed = After sending 18x response, the remote client
waits before sending RTP (e.g., Microsoft Lync
environment). For the device's handling of this remote UA
support, see Interworking SIP Early Media.
Defines whether the destination UA can play a local ringback
tone.

[0] No = UA does not support local ringback tone. The
device sends 18x with delayed SDP to the UA.

[1] Yes = (Default) UA supports local ringback tone. For the
device's handling of this remote UA support, see
Interworking SIP Early Media.
Defines whether the destination UA is capable of receiving 18x
messages with delayed RTP.

[0] Not Supported = (Default) UA does not support receipt of
18x messages with delayed RTP. For the device's handling
of this remote UA support, see Interworking SIP Early
Media.

[1] Supported = UA is capable of receiving 18x messages
with delayed RTP.
Determines whether multiple 18x responses (including 180
Ringing, 181 Call is Being Forwarded, 182 Call Queued, and
183 Session Progress) are forwarded to the caller.

[0] Not Supported = Only the first 18x response is forwarded
to the caller.

[1] Supported = (Default) Multiple 18x responses are
forwarded to the caller.
