Session Expiration	Grandstream implemented SIP Session Timer. The session timer extension
	enables SIP sessions to be periodically “refreshed” via a re-INVITE request.
	Once the session interval expires, if there is no refresh via a re-INVITE
	message, the session will be terminated.
	Session Expiration is the time (in seconds) at which the session is considered
	timed out, if no successful session refresh transaction occurs beforehand. The
	default value is 180 seconds.
Min-SE	The minimum session expiration (in seconds). The default value is 90 seconds.
Caller Request	If selecting “Yes” the phone will use session timer when it makes outbound
Timer	calls if remote party supports session timer.
Callee Request	If selecting “Yes” the phone will use session timer when it receives inbound
Timer	calls with session timer request.
