I know, I know that I should do a pjsip trunk between my point to point FPX boxes but IAX has just worked. I just did an install of FPX 15 on an unknown celeron micro ITX board off of eBay and did a restore from a backup of my current fully functioning FPBX system. I must tell you the restore was perfect. Everything I had entered and set was there in the restored PC. I have compared every and I mean every setting of both FPXes… multiple times.
My Flowroute PJSIP trunk and my SIP trunk work fine, all extensions work great, calls in and out via the PSTN work great no issues. Well I never did check my IAX and today when I did, “all circuits are busy”. No joy in or out via IAX. Both remote and local have the same message and can’t connect
Both ends show IAX connected. Remote end is a FPBX 14 and local are both15, both the backed up and restored boxes. I reset both FPXes both firewall routers (VPN into the remote site) and no joy. I then scoured the aaterisk full log. No real errors other than cannot connect to an endpoint or no endpoint found or similar logged message/error. Like no connection at all was present or created. After no endpoint found it would then go through the hang up sequence and play the congestion message also seen in the log.
When I put my backed up… the old FPBX, back in the network, it all works just fine.
Any thoughts and what’s missing? From both ends IAX shows connected. Ping and response times show good. The new FPBX uses the same IP, with the old one shut down.
Hope all this makes sense and again, thank-you so much for any thoughts. What did I and/or the backup/restore miss?
