SIPAddHeader() — Adds a SIP header to the outbound call


SIPAddHeader(Header: Content)

Adds a header to a SIP call placed with the Dial() application. A nonstandard SIP header should begin with X-, such as X-Asterisk-Accountcode:. Use this application with care—adding the wrong headers may cause any number of problems.

For more flexibility, see the SIP_HEADER() dialplan function.

exten => 123,1,SIPAddHeader(X-Asterisk-Testing: Just testing!)
exten => 123,2,Dial(SIP/123)
