Re: [SR-Users] Send SIP Info within a dialog using $uac_req(method)="INFO"

Hello, Ok great thanks Daniel. One final thing, I cant seem to get kamilio to except the parameter when I add the socket parameter in the kamctl mi t_uac_dlg command. If I add as below I get 404 invalid local socket; kamctl mi t_uac_dlg INFO sip:3003@193.144.1.112 . udp:10.70.1.136:5060 \"From:sip:1234@8.8.8.8"\r\nTo:sip:3003@193.144.1.112\r\nContact:sip:daemon@8.8.8.8\r\n\"" 404 Invalid local socket As its picking up the socket with the from address included as well, is this again around syntax?

One can start the function parameters with single quote, then double quotes don't need to be escaped. Other blackslashes need to be escaped and it this case you need more because you want to propagate then to the command line.
