Affordable and robust PBX system

Dissatisfied

5+ Years Installing and Supporting 3cx

What do you like best? The flexibility of its deployment and agnostic use of SIP Trunks and hardware What do you dislike? The technical support really needs some work. This has been a point of contention since day 1, 5 years ago and has really never improved. The staff there are difficult to work with and often are very unhelpful. Extremely unhelpful would be best described. Almost instructed to be as unhelpful as they are. We have basically had to learn on our own through trial and ...

What benefits have you realized? Cost savings, valued feature additions.
