I am running into an issue with one of our systems. There are random times when one extension cannot call another, it will just go to voicemail. It is only one or two extension that cannot call one or two others at a time.
We are running FreePBX Dirsto 5.211.65-14
Confirmed all modules are up to date.
All phones are offsite.
Able to reproduce the issue from different locations
Non of the called phones are showing offline, unreachable, busy or DND.
At the bottom of the call log output I get
