Bonjour, 
Today, Network issue for me.
The goal: Convert this docker-compose to Hashistack.
It’s a docker for Asterisk + FreePBX.
I have already a MariaDB with Consul Service Mesh running and OK.
After severals tests, I achieve a good result, I can reach FreePBX WebUI. I can create users (named extensions in asterisk).
My iOS and macOS apps can connect to server.
So I make a call, it rings, I pick up and… No sound, and It hangs, and in logs, this error:
Disconnecting channel 'PJSIP/100-00000004' for lack of audio RTP activity in 30 seconds
This error is knows as a network issue.
Asterisk need lots of open ports. In my case, I use port range from 18000 to 18100.
In Nomad Job, it looks like:

I don’t know why there is no activity on ports named freepbxrtp000...
I use tcpdump portrange 18000-180100 and nothing appears.
But when I use: tcpdump port 5060 I can see activity with connections between peers.
I tried in other VM, as explained on izDock Github.
It works out-of-box and tcpdump reveals traffic between port range 10000-20000.
Why I can see activity on port 5060 and not on other in range?
I reduce numbers of rtp ports. But it doesn’t work anymore.
Should I hang up a call from Nomad and only pick up the song from Docker-Compose?
Thanks!
