I haven't really used swyx but have a friend who uses it and by the sounds of his setup its not a great system, is it bad or is it just configured wrongly, he sometimes struggles to get two calls at the same time, I told him to just bin it and go to 3cx but he has invested quite a lot in the system and would like to get it working,
what's everyone's thoughts on swyx as a reliable VoIP PBX?
