Hi I would like send an event from LUA to a phone, with this header: Event: x-gs-screen (This message makes the Grandstream phone refresh its Idle-Screen) I tried this: eout = freeswitch.Event("NOTIFY"); eout.addHeader(eout, "profile", "mellek-belso"); eout.addHeader(eout, "to-uri", "sip:50@192.168.1.10"); eout.addHeader(eout, "from-uri", "sip:50@192.168.1.10"); eout.addHeader(eout, "event-string", "x-gs-screen"); eout.fire(eout); and played with it a lot, e.g. add more headers, change the IPs, ... but the SIP message does not arrive to the phone, altough there are not any error message. How can i do this? Thanks
