I am using x-lite to connect to virtualpbx.net. One of my user's x-lite is stuck at offline and the availability dropdown box is grayed out. I don't see any error messages in x-lite or virtualpbx.net. He can still make outgoing calls.
I didn't setup this system and don't know much about VOIP phones, etc. Everytime I google x-lite or virtualpbx i get sales pages. I've looked at https://support.counterpath.com/ but don't see anything there.
