Field Description
Register Settings
Reregister every The time interval between X-Lite’s attempts to reregister in order to refresh the account
registration with the VoIP service provider for this account. A value of zero means not to
reregister after the initial registration.
This value is placed in the “Expires” header field of the REGISTER message.
Minimum time If the reregistration fails, X-Lite will wait this amount of time, then attempt to reregister. If the
second attempt fails, X-Lite will wait twice this time and try again, then four times this time, and
so on, until reregistration succeeds.
Maximum time This is the maximum wait time between attempts to reregister. Once this maximum is reached, X-
Lite will wait this time for all subsequent attempts.
For example, the min. time is 20 secs, the maximum time is 120 secs. X-Lite will attempt to
reregister as follows:
• Wait 20 secs.
• Attempt to connect.
• If fail, wait 40 secs.
• Attempt to connect.
• If fail, wait 80 secs.
• Attempt to connect.
• If fail, wait 120 secs (the maximum)
• Attempt to connect.
• If fail, wait 120 secs, and so on.

then reset.
• Turn on to enable session timer. Enter a value in Default session time.
• Turn off to disable session timer; refreshes will never be sent.
