Hi! I want to show the red "unavailable" Icon in the 3CX Client when somebody hits the DND Key. I´ve tried with the http api: http://192.168.x.x:5484/PbxAPI.aspx?func=upd_ext&extnum=<extension>&pwd=<pass>&disable=1 So if a user hits the dnd (on) key, it opens that url. The Phone is not available then, but in the 3CX Client there is no change of the status at all. Im using actions URL´s for other functions too, there is an asp.net script running, so if the solution is to work with the 3cx API, i could do it, i just need a little hint were to search Thanks in advance!
