Hello there, I had setup a test lab with V15.5, had couple window clients provisioned which worked fine. I had to restart the computer & now it has a different internal IP address & phones no longer work. Outside facing IP is static but internal seem to keep changing. After reading I un-installed & reinstalled with backup copy...but same thing. I didn't get option for static IP for internal IP. Can someone advise a fix pls? Having to re-provision phones every time computer starts is no fun lol. Thank you in advance.
