I’m trying to make work my elastix and cisco IP phone and i have the following problem: With the following comand the phone ring asterisk -rx “originate SIP/315@XXX.XXX.XXX.XXX application Playback hello-world” But with the following one, the phone doesn’t ring asterisk -rx “originate SIP/315 application Playback hello-world” I mean, if i don’t write the ip\_addres, the phone doens’t ring. I have been analyzing it in wireshark, and i detected: This is the output for the firs command: 5060 315.135647000 192.168.10.1 192.168.10.20 SIP/SDP 830 Request: INVITE [sip:315@192.168.10.20](mailto:sip:315@192.168.10.20) | 5060 8534 And this one for the second: 5060 39.117858000 192.168.10.1 192.168.10.5 SIP/SDP 808 Request: INVITE sip:192.168.10.5 | 5060 868 The difference between them is after INVITE sip. Does any body how should i configure elastik in order to make it word just with the command: asterisk -rx “originate SIP/315 application Playback hello-world” For sure, that is a silly hing, but i can’t get it. Any suggestion? Regards
