PJSIP_HEADER_PARAM()¶
Synopsis¶
Get or set header/URI parameters on a PJSIP channel.
Description¶
PJSIP_HEADER_PARAM allows you to read or set parameters in a SIP header on a PJSIP channel.
Both URI parameters and header parameters can be read and set using this function. URI parameters appear in the URI (inside the <> in the header) while header parameters appear afterwards.
Note
If you call PJSIP_HEADER_PARAM in a normal dialplan context you'll be operating on the caller's (incoming) channel which may not be what you want. To operate on the callee's (outgoing) channel call PJSIP_HEADER_PARAM in a pre-dial handler.
