We have 1 3cx install and we would be adding another if they would add 1 simple feature. The ability to have multiple greetings per extension. Our current outdated Toshiba PBX allows the user to have multiple greetings stored in the system. They can come in on Monday and setup a new greeting for every day of the week. They can set an away greeting for days that they will be out of the office and have it automatically switch back on the next day or the same day if they are returning that day. Mind you it is a little cumbersome to setup, nonetheless the feature is there. We're replacing that Toshiba system with a Cisco system that has similar features. 3CX would be our choice if it had this. I'd put this on ideascale but I can't remember my password and the forgot password option never sends me another email. Not to mention that there is stuff on there that has been in progress for 2 years and isn't complete. 3cx is a great product, but I feel it is missing fundamental features. It's a shame really, 3cx is much more affordable than Cisco.
