Hello, I have a FreePBX system doing all of my Physical Extensions, as well as my main trunking, DIDs, etc. I don't care for any of the available smartphone clients, however, for Asterisk/FreePBX. I took a "test drive" of 3cx almost a year ago, using the free "PBX Edition" license. The iOS and Android clients work excellently with 3cx! I am now trying to test out a Hybrid environment, using the free 3cx license for soft phones, and FreePBX for everything else. I've googled several different search terms, as well as searching these forums directly. The only info that seems somewhat relevant is for an old and now outdated version of 3cx. Are there any more current instructions? I am using a slightly outdated version of FreePBX/Asterisk, specifically: IncrediblePBX 12.0.74/Asterisk 13.18.0 . I am using the latest 3cx, however, as of this writing (specifically 15.5.6354.2).
