Hi,
You did not need the Asterisk forums to know that, it has been said multiple times (and even recently) here as well…
As said in this thread (starting from this post down), you can report problems with PHP 7 but it will take quite a while before it is supported.
The FreePBX devs are fully able to make their code PHP 7 compatible, the problem is definitely not there. The problem is a dependency, for commercial modules, to something which is no longer supported for PHP 7… There’s a big difference…
They have to find a suitable replacement before even considering going to PHP 7…
Have a nice day,
Nick
