20.1.2 SIP Endpoints
Shows the sessions that are currently being managed by ALG.
This includes static entries to make internal SIP servers/proxies (e.g. internal Asterisk serv-
er) accessible from the WAN (Internet) by NAPT. In addition, internal SIP clients without re-
gistration can be made accessible using a static entry. All active SIP sessions that have
been initiated from internal SIP terminals are recognised dynamically and listed here.
These are only displayed for monitoring and administration and cannot be edited.
Note
All automatically created entries that are not used for longer than 24 hours are auto-
matically deleted from the table.
20.1.2.1 Edit or New

cessible by terminals from the WAN across the NAPT barrier. Choose the
icon to edit
existing static entries.
