Not sure if there’s any changes by now. But some community members said that FreePBX 15 works best with all modules on the latest edge releases.
But I do agree that it takes now very long for reported bugs to be addressed.
For example, this whole IVR Force Strict Dial Timeout is one big mess. Finally the “No - Legacy” was released, but now you can dial ANY extension in an IVR, no matter if you set Direct Dial to a Directory or Disabled.
I also reported a bug a long time ago: Queues allows you to set Skip Busy to Yes.
It works perfect in a scenario where you have a single “Operator” answering calls in the order they were received and don’t want to be bothered by external callers while on the phone.
All works great until the operator transfers a call that came from the queue to an extension who’s already on the phone, it basically preserves the Skip Busy even when transferred out of the queue and goes to that person’s voicemail.
Both issues are, what some of our clients struggle on daily basis.
IMO: The IVR “No - Legacy” is quite of a security risk. If someone figures out your doorbell extension and the DTMF code they can open your door now…
