Hi, I’m a novice to phone systems and have installed freePBX and Cisco SPA504G phones with Sipgate basic package. We have 4 phones, and one number, as we are only using Sipgate basic there is no trunking option from freePBX so each phone is set to talk straight to Sipgate on one ext and to freePBX on another ext so we can ring from one phone to another. What we can’t do is transfer calls from one to another, getting call declined when trying. It did previously work until we moved offices and re-installed everything.
