equal to one-third (1/3) of the Session-Expires value. If the refresher
does not send a refresh request within the new timeout, the device
disconnects the session (i.e., sends a SIP BYE).
For example, if you configure the parameter to 32 seconds and the
Session-Expires value is 180 seconds, the session timeout occurs 148
seconds (i.e., 180 minus 32) after the last session refresh. If the
Session-Expires header value is 90 seconds, the timeout occurs 60
seconds after the last refresh. This is because 90 minus 32 is 58
seconds, which is less than one third of the Session-Expires value
(i.e., 60/3 is 30, and 90 minus 30 is 60).
The valid range is 0 to 32 (in seconds). The default is 32.
Determines the SIP method used for session-timer updates.

[0] Re-INVITE = (Default) Uses re-INVITE messages for session-
timer updates.

[1] UPDATE = Uses UPDATE messages.
Notes:

The device can receive session-timer refreshes using both
methods.

The UPDATE message used for session-timer is excluded from the
SDP body.
Determines whether the device removes the 'to' header tag from final
SIP failure responses to INVITE transactions.

[0] = (Default) Do not remove tag.

[1] = Remove tag.
Enables the use of the 'rtcp' attribute in the outgoing SDP.

[0] = Disable (default)

[1] = Enable
Note: This parameter is applicable only to the Gateway application.
Defines the user part value of the Request-URI for outgoing SIP
OPTIONS requests. If no value is configured, the configuration
parameter 'Username' valueis used.
A special value is 'empty', indicating that no user part in the Request-
URI (host part only) is used.
The valid range is a 30-character string. By default, this value is not
defined.
Enables the device to not respond to received SIP OPTIONS
messages from, and/or send keep-alive messages to, a proxy server
associated with Trunk Group ID 1 if all its member trunks are down.

[0] = Disable (default)

[1] = The device does not respond to SIP OPTIONS received from
the proxy associated with Trunk Group 1.

[2] = The device does not send keep-alive messages to the proxy
associated with Trunk Group 1.

[3] = Both options [1] and [2].
Notes:

When this parameter is set to not respond to SIP OPTIONS
received from the proxy, it is applicable only if the OPTIONS
message does not include a user part in the Request-URI.

The proxy server is determined by the Proxy Set that is associated
with the Serving IP Group defined for the Trunk Group in the Trunk
