Max. time This is the maximum wait time between attempts to reregister. Once this maximum is reached,

X-Lite will wait this specified time before all subsequent attempts.

For example, if the minimum time is 20 seconds and the maximum time is 120 seconds, X-Lite will

attempt to reregister as follows:

• Wait 20 seconds

• Attempt to connect

• If attempt fails, wait 40 seconds

• Attempt to connect

• If attempt fails, wait 80 seconds

• Attempt to connect

• If attempt fails, wait 120 seconds (the maximum)

• Attempt to connect

• If attempt fails, wait 120 seconds

•etc.

The factory setting is 1800.

Send SIP keep-alives Typically checked, to instruct X-Lite to send SIP keep-alive messages for maintaining a “pinhole” in

the user’s firewall through which SIP messages can pass.

Use rport Typically checked.

Enable session timers A session timer is a mechanism to detect—from a signalling perspective—whether a call session is

still active. When the timer expires, one party in the call sends a refresh to the other party and the

clients reset the timer.

• Check to enable session timers. If desired, enter a value in Default session time (the factory

setting is 60).

• Uncheck to disable session timers; X-Lite will not send refreshes.

Session timer preference This field specifies which party should send session timer refreshes during communication. The

preference is not a guarantee that the specified party will perform the refresh. Choices are:

• None: No preference

• Local refreshes: The local computer sends refreshes

• Remote refreshes: The remote party sends refreshes

• UAC refreshes: The user agent client sends refreshes (i.e. the party that initiated

establishment of the current communication)

• UAS refreshes: The user agent server sends refreshes (i.e. the party that received the initial

request for the current communication).
