What’s a Trusted IP?
Lots of big PBXes are not able to authenticated itself with username and password. They assume an authentication via IP address. With a Trusted IP, you can decide from which IP addresses your PBX is allowed to log in a trunk. The use of this feature is only possible with a static IP.
