I am very new to Free PBX and have just installed the version availble on raspberry-asterisk dot .org /downloads/ onto a raspberry pi 3.
I have set up two extensions and a trunk.
When I call between extensions, the call gets forwarded to voicemail after a while which is great.
When I call from an outside line, the call rings for a while and then stops ringing but does not get forwarded to voicemail. The phone I’m calling from sort of just goes quiet (stops ringing tone but connection still seems active)
The version I have installed doesn’t seem to have any call forward features that I can see? What am I missing here? why would the call being going to voicemail from an internal call but not external?
I should also mention that for some reason I can’t get my outbound calls working as yet - not sure if that has anything to do with it but as I say, internal calls are going to voicemail and inbound calls are working.
That is my next problem to solve after I can get this voicemail forwarding working!
It sounds like your NAT and RTP configuration are suspect. I’d start looking at your firewall and your SIP configuration to make sure everything is set up correctly.Search the forum for “one-way audio”. That should get you started.
