It has been suggested that the issue with being able to make calls out or accept calls in might have something to do with one (or combination) of:
- Firewall
- Port Forwarding
- NAT
Re 1), I have disabled my firewall on this, my development server, so it is not that.
Re 2) I have not forwarded any Ports through my router. I am not accepting connections from any location other than the Trunk Provider(s) and since I am reaching out to them, I did not think I needed to forward any Ports. I have the same setup now with my existing PBX and it is working fine. However, if the Wazo setup requires any Ports forwarded, can you let me know?
Re 3) I have added to the SIP General Settings the following:
nat => force_rport,comedia
externip => {my actual public IP}
localnet => 192.168.1.0/255.255.255.0
Which is in addition to the Options I added in the Trunks for the one provider as per their specs:
buggymwi: no
nat: force_rport,comedia
insecure: port,invite
rtptimeout: 60
rtpholdtimeout: 300
allowoverlap: no
allowtransfer: no
progressinband: no
disallow: all
allow: ulaw
directmedia: no
And I also connected Wazo to another Trunk provider I use without the above additonal Trunk Options
Unfortunately, no change for either Trunk povider
Internal calls work fine
Calls In or Calls out come back with error message Unreachable or Busy
Any suggestions are appreciated
