I'm trying to use an FXS port as a paging extension but when I go to the "FXS/Voip Extensions" section under "PBX" It says "No FXS Extensions Defined"
I can't seem to find a place to add and FXS extension. Can you tell me how to do so? It comes with 8 PTSN ports so I shouldn't have to add any hardware to utilize those ports right?
