Can I use the PBX of my Quintum to make a call to another Quintum(PSTN) in my LAN? Lets say I want my Quintum A’s PBX(via regular telephone) to make a call to Quintum B’s PSTN? Is it possible? Because I config Quintum A’s Static Route(destination IP, DNs, etc) but the calls wont connect it just routes to Quintum A’s PSTN.. can it be done? I read in this thread that I need to use a ATA box to this in the same network unless its via IP.
