Synopsis: FreePBX 15 on local LAN behaind NAT firewall/router. Attempting to register a PJSIP/Trunk from FreeSwitch Server on a VM on the same LAN. I am using username/password for authentication.
I can regster a softphone to an extension but cannot register from FreeSwitch. Consistently receiving SIP error: “registration failed - 404 Not Found”…
I can register to the FreeSwitch from PBX okay, but not FS to PBX.
I have stopped iptables/fail2ban, checked ports and reviewed router/firewall but problem persists
Could anyone advise please?
