I'm just trialling this PBX stuff. I have 2 Raspberry Pi. One running Raspbx(Asterisk 11.21.0/FPBX 13.0.51) and one running IncrediblePBX(asterisk 13.7.2/FPBX 12.0.70), I have 2 extensions set up on each for testing purposes. Just to be clear these are totally separate systems, I am not trying to call from one to the other. I have an issue with the IncrediblePBX in that it will not go to voice mail if the called ext is not answered. If I reject the call from the called ext it will then go to voice mail so the voice mail system is clearly working. The ringtime default in advanced settings is 15 secs, I have tried setting it per extension but still no luck. I am at a loss as to why the system will not go to voice mail at the end of the ringtime. Can anyone suggest a setting I might check.
