I am using 3CX V12 SP6 in one 2008R2 standard server. Every reboot the 3CX tunnel in port 5090 doesn't listen even if you can see its started. Using TCPview from SysInternals, the process is listening in port 5080. A simple process restart from 3CX system management console is enough to bring port 5090 up and keep 5080 also up. I don't know when it started. Any ideas to bring it up always?
