I think your "Signal= '2'" should be changed to "Signal= 2". Also, this may be obvious, make sure you have an empty CRLF line between the SIP message header and message body. So, showing invisible characters, you should have: Content-Type: application/dtmf-relay<CR><LF> ContentLength: 26<CR><LF> <CR><LF> Signal= 2<CR><LF> Duration= 250<CR><LF> Note also that the content-length above is 26.
