I´m on my final year of 12th grade (portugal), ad i a an intern on a buiseness and my function is to build and implement a voip server so the workers can call between themselves, do outbound calls and recieve inbound. I have installed: UBUNTU SERVER 12 LTS as base os Asterisk 11.3.o as pbx and finnaly FreePBX 2.10 The network is set and the extentions too Screencap so the problem is: When i try to connect the softphone 3CX to the PBX i get a "authentication failed" error Here is the debug console Screencap and the profile configurations Screencap so once again, the proble is , i cant authenticate on the pb server, how can i resolve this problem ? Help please. if it is needed any other logs warn me and i will provide.
