4.12 Currently Handled UA

This table shows the currently handled UA with their SIP URI and their associated IP address. The third column shows the SIP request type that this binding is using. Typically, this will be a REGISTER or SUBSCRIBE request.

User agents may have more than one entry. In this case, they might have dangling registrations on the registrar; this typically happens when the call-id is changed during a re-registration. From the NAT Filter point of view, this is no reason for concern.

It is ok if user agents show up several times. This typically indicates that the user agent tries to register several times, possibly on different proxies or after rebooting. The logic of the filter will make sure that only one refresh per destination occurs.

Please remember that calling this web page on a large installation would block the system for a potentially long time. Therefore, we limited the display to the first hundred registered user agents. You will see three dots at the bottom of the screen. If you want to check which user agents are registered on your system, you should check the registration log file instead.

4.13 Memory Statistics

This web page shows information about the current memory usage. The primary goal is to identify situations when the process grows more than expected. Usually, the NAT Filter process should not take more than five megabytes.
