Hi to you! In fact I would like to connect 2 servers Elastix (A and B) and 1 server (C) astériknow. Indeed, when I connect the different servers with SIP trunk, I can not give off calls between different servers! Does someone could help me please? I also want to know why after you specify the "trunk sequence: this has no effect? because communication between two servers is possible but not when you want to call an extension of A to C or C to B such as in the "Trunk Sequence" it only takes into account that the first trunk specify! Thank you in advance!
