Hi Boss, I can help diagnose and fix your FreePBX 15 SIP trunk registration issue behind Kamailio SBC, including authentication, SIP headers, codecs, NAT/SIP settings, and outbound call routing. I have experience troubleshooting Asterisk/FreePBX SIP trunks and SBC routing issues, and I can work via AnyDesk as requested. After fixing it, I’ll provide a short step-by-step summary of what was changed so you can replicate it later. Price: €25 Delivery time: 1 day Important question: Do you already have the SIP provider’s required settings for registration, outbound proxy, codecs, and caller ID format?

Successfully registering a SIP trunk through Kamailio and FreePBX requires careful attention to authentication and routing—it's often a delicate interplay. I’ve previously troubleshooted similar setups involving Asterisk and SBCs, ensuring proper SIP signaling and codec negotiation for reliable call connectivity. I’ll use Anydesk to examine your FreePBX 15 configuration, Kamailio routing rules, and SIP trunk settings to pinpoint the registration failure and adjust authentication, codecs, and headers as needed. I anticipate being able to diagnose and resolve the registration issue within 4-5 days, with the remaining time for documentation and testing. Could you share the provider's SIP URI format they require?
