In contrast to previous versions, the time related settings have been summarized on this new management web page. The filter differentiates between registration related settings and call related settings.

4.4.1 Register Timeouts

The Refresh Interval for the UA is the number of seconds between NAT refreshes from the NAT Filter. The NAT Filter keeps track of registered user agents and keeps their NAT port binding alive with pack- ets. Typically, a port timeout is 60 seconds; however, because this value must handle the smallest timeout, a value of 15 seconds seems more ap- propriate. The filter sends the keep-alive packets regardless of the trans- port layer. Although on TCP most implementations keep the connection alive for a much longer time, some implementations close their ports after a short timeout. Therefore, TCP connections must also be refreshed.

The Registration Logging Time is the time after which it moves the backup file to the primary location. See preparing recovery above.
