As a Callee, select UAC to use the caller or proxy server as the refresher, or
select UAS to use the phone as the refresher.
The Session Timer can be refreshed using the INVITE or UPDATE methods.
Select "Yes" to use the INVITE method to refresh the session timer
The default setting is Yes. If Yes is selected, the phone will use the session timer
when it makes outbound calls if remote party supports session timer.
If Yes is selected, the phone will use the session timer when it receives inbound
calls with session timer request.
If Yes is selected, the timer will be activated even if the other party does not
support session timers. If No is selected, the timer will be activated only if the
other party supports the timer. To disable the timer, Caller Request timer, Callee
request timer and Force Timer should all be set to No.
The use of the PRACK (Provisional Acknowledgment) method enables reliability
to SIP provisional responses (1xx series). This is very important in order to
support PSTN internetworking. To invoke a reliable provisional response, the
100rel tag is appended to the value of the required header of the initial signaling
messages. The default setting is No.
Selects the SIP transport method. There are three types: TCP, UDP and TLS.
Selects whether or not symmetric RTP is supported.
Selects whether or not SIP Instance ID is supported.
This configuration selects whether or not the incoming messages should be
validated.
This configures the timeout period for SIP T1. The default setting is 0.5 Seconds
This configures the time interval for SIP T2. The default setting is 4 seconds.
The SIP Extension notifies the SIP server that it is behind a NAT/firewall.
--YES: Accepts all incoming video, this is the default setting;
--NO: video is disabled.
--Enable/Disable during dialing: Dialing time choice to enable/disable video
Assigns the mechanism to send DTMF. There are three supported modes: in
