Hi everyone, I am trying to send SMS via python script but not working, I followed the script in confluence from ESL import * con = ESLconnection("127.0.0.1", "8021", "ClueCon") if con.connected(): event = ESLevent("CUSTOM", "SMS::SEND_MESSAGE") event.addHeader("to", "1000@192.168.1.6") event.addHeader("from", "5000@192.168.1.6") event.addHeader("dest_proto", "sip") print(event.serialize("plain")) event.addBody("message contents") con.sendEvent(event) as result of print command I get : Event-Name: CUSTOM Event-Subclass: SMS%3A%3ASEND_MESSAGE to: 1000%40192.168.1.6 from: 5000%40192.168.1.6 dest_proto: sip but no message received in 1000 extension.
