I agree with you 100% Baulder. That is a flaw of Fusionpbx. There should be an option to clone existing domain, then you simply add the necessary extensions. Especially the "gateways" and " routing. I use the same gateways for every new client. Anyways, Freepbx has its good, the bad and the ugly and so does Fusion PBX. Those are the two I have used and have found that Freepbx has more support and more flexibility. The only reason I tried to use Fusionpbx was for the multi-tenant. But since the call strategy "rollover" does not work as designed I can't even use fusionpbx anymore. I could pay for support and would be glad to do it. But I have little confidence they could make something work that is not working now, therefore wasting my tech support money. I guess I am just frustrated. It should work but doesn't. It is supposed to try the first extension then "rollover" to the next ext if busy. Instead it just shows call waiting on the first extension. I even turned of CW in the phone itself (spa525g2) and it still does not roll over. Wish they would fix a few minor things and I would sing praises about fusion. Until then back to multi existences of freepbx
