Let’s assume I have three freepbx system A B C
System A has two IAX trunk, the one to system B and the other to system C
From system A i can call directly system B or C extensions and vice-versa
How (if possible) can I call system B extensions from system C and vice-versa without a trunk between B and C systems ???
(let’s say system A is the center of a star network)
Is there any feature (like in Avaya systems is called “small community network”) that automatically instruct and share about resources of the pbx network ??
