Just got some new Mitel 5634 phones that I am trying to hook up to teleworker and having some issues that I can't figure out.
I have it successfully connected to teleworker from outside the building (shows connected in MBG), but when I try to make a test call it just beeps and states "NO CHANNELS AVAILABLE."
Attached is how I have SIP configured in WinPDM, but hard to find any information on this setup anywhere.
