This setup provides a reasonably secure method of connecting two Trixboxes together over an IAX2 trunk. Registration is not required because static IP addresses are employed on both Trixboxes.
To limit the number of concurrent connections over the trunk a maximum number of channels must be specified or it should be left blank for unlimited connections. Dial Rules need to be set up for all digit strings that will pass over the trunk.
An outbound route will also need to be set up to route calls to the trunk. Caller ID is forwarded normally. Beware of using the same numbers on each Trixbox, the caller ID name from the wrong Trixbox might be displayed.
