Hello, I try to control the LEDs on Snom 370 phones using LUA and event type SEND_MESSAGE. The phone receives this message: MESSAGE sip:2850@85.16.245.213:1051 SIP/2.0 Via: SIP/2.0/UDP 85.16.246.6;rport;branch=z9hG4bKeer7H9cFa85DN Max-Forwards: 70 From: <sip:2850@85.16.246.6>;tag=yH2p954XZZ1tj To: <sip:2850@85.16.246.6> Call-ID: 2a6ed9ba-ef6d-122d-3d83-00144fe6e332 CSeq: 131979517 MESSAGE Contact: <sip:mod_sofia@85.16.246.6:5060> User-Agent: FreeSWITCH-mod_sofia/1.0.head-17097:17188M Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, UPDATE, INFO, REGISTER, REFER, NOTIFY, PUBLISH, SUBSCRIBE Supported: timer, precondition, path, replaces Content-Type: application/x-buttons Content-Length: 10 k=1 c=on and Snom acknowledges this with 200 OK. Unfortunately nothing happens. Snom's howto (http://wiki.snom.com/Category:HowTo:LED_Remote_Control) describes a message like this: MESSAGE sip:44@172.20.25.101:2048;transport=tls;line=44qsudyt SIP/2.0 Via: SIP/2.0/TLS 172.20.25.102:5061;branch=z9hG4bK-2909fe081f8466c9836c3b673f284842;rport From: <sip:44@localhost>;tag=17820 To: <sip:44@localhost> Call-ID: umceg9jb@pbx CSeq: 35160 MESSAGE Max-Forwards: 70 Contact: <sip:172.20.25.102:5061;transport=tls> Subject: buttons Content-Type: application/x-buttons Content-Length: 7 k=3 l=42 Main difference is the subject header containing "buttons" (despite of the body) Is there a way to add subject header as above to the message generated by FS? regards Helmut
