Hey guys, i am currently updating a clients FreePBX software to the latest stable version. However after about forty minutes to an hour FreePBX will loose the connection. All calls incoming will get routed to his cell phone (set up through trunk service in case of VOIP failure) all out going calls will get the message that all circuits are busy now. I have added the Freepbx box to the routers dmz and forwarded ports 5060-5065. I have tried to copy every setting the same as his older freePBX setup is over ten years old. Researching i read that i may need to change the sip connection setting to insecure=port,invite as it is set to insecure=very. Beyond this i cant think of or find anything that different in the system. I have noticed that if the connection loss occurs i can regain connection by either rebooting the server or by selecting submit from the web GUI and apply config on any page. Im not sure why the later one works though. I AM NOT VERY FAMILIAR CONFIGURING FreePBX, i have copied a part of the log file below please let me know if you need anything additional and if so how to generate it. I printed out the below logfile and took it home just for research its a lot to key in so today i will stop by the office and get a softcopy of it to add below.
