Configures the phone system's SIP session timer. It enables SIP sessions to be
periodically "refreshed" via a SIP request (UPDATE, or re-INVITE). If there is no
refresh via an UPDATE or re-INVITE message, the session will be terminated once
the session interval expires. Session Expiration is the time (in seconds) where the
session is considered timed out, provided no successful session refresh transaction
occurs beforehand. The default setting is 180. The valid range is from 90 to 64800.
Determines the minimum session expiration timer (in seconds) if the phone act as
a timer refresher. The default setting is 90. The valid range is from 90 to 64800.
Sets which party will refresh the active session if the phone makes outbound calls.
If it is set to "UAC" and the remote party does not support Refresher feature, the
phone system will refresh the active session. If it is set to "UAS", the remote party
will refresh it. If it is set to "Omit", the header will be omitted so that it can be selected
by the negotiation mechanism. The default setting is "Omit".
Specifies which party will refresh the active session if the phone receives inbound
calls. If it is set to "UAC", the remote party will refresh the active session. If it is set
to "UAS" and the remote party does not support refresh feature, the phone system
will refresh it. The default setting is "UAC".
Sets the SIP message type for refresh the session. If it is set to "Yes", the Session
Timer will be refreshed by using the SIP INVITE message. Otherwise, the phone
system will use the SIP UPDATE or SIP OPTIONS message. Default is "No".
Sets the caller party to act as refresher by force. If set to "Yes" and both party
support session timers, the phone will enable the session timer feature when it
makes outbound calls. The SIP INVITE will include the content "refresher=uac".
The default setting is "No".
Sets the callee party to act as refresher by force. If set to "Yes" and the both parties
support session timers, the phone will enable the session timer feature when it
receives inbound calls. The SIP 200 OK will include the content "refresher=uas".
The default setting is "No".
Configures the session timer feature on the phone system by force. If it is set to
"Yes", the phone will use the session timer even if the remote party does not
support this feature. If it is set to "No", the phone will enable the session timer only
when the remote party supports this feature. To turn off the session timer, select
"No". The default setting is "No".
Actives PRACK (Provisional Acknowledgment) method. PRACK improves the
network reliability by adding an acknowledgement system to the provisional
Responses (1xx). It is set to "Yes", the phone system will response to the 1xx
response from the remote party. The default setting is "No".
Specifies which header tag will be used from the SIP INVITE message for the Caller
ID display. If it is set to Auto, the phone system will use the one of the available
headers in the priority hierarchy of P-Asserted Identify Header, Remote-Party-ID
Header and FROM Header. If it is set to "From Header", it will use the FROM header
