As others have expressed in various locations thus far today, 3cx v15.5 SP3 Standard has removed the option to use your own FQDN and SMTP for new customers. For the time being, existing installs that are upgraded do not require a change, but how long will that last? As a 3cx hosting provider, this is a major step backward. Requiring us to procure the PRO edition to maintain our branding and features that, as of yesterday, were in Standard is NOT OK. I would encourage you to provide feedback to your distributors, channel managers, and whomever else you know at 3cx to have them reconsider this significant step backward. It is clear in these forums that people are not happy with the change yet the 3cx members of the forum are taking a very flippant attitude trying to tell us how this is such a great change. Sorry, the only improvement in this change is going to be to 3cx's bottom line at the cost of our own bottom lines. That is not OK. I'm not a huge company yet, but if this mistake is not corrected, all of my current and future installs will move to another platform. I hate to lose my capital and intellectual investment into this platform, but I'll be damned if I'm going to get fleeced for simply using my own FQDN and SMTP servers.
