Hello, I'm new of 3CX and I have a question. I have a 3cx pbx and a Door station of Lilin with a relay that open a door. It is SIP and the audio/video work good. The Lilin door station haven't a dtmf code to open relay but have only a string http to open relay like this: Code: http://192.168.0.200/setio?relay1=1 and http://192.168.0.200/setio?relay1=0 to stop the opening. Is possible to program 3CX to assign a code (for ex: *123) to launch that string ? Thanks in advantage and sorry for my bad english.
