But to give a bit more context, the Kamailio architecture related to SIP message processing is optimized to avoid re-parsing of the message during configuration processing. This works with so called "lumps" which are more or less like a programming patch file (e.g. change, delete parts). This lumps are applied shortly before sending the message out or if you call msg_apply_changes(). Some parts of the SIP message are accessed directly, because they are "more important" (like the request URI) are handled specially, some like the From user are done like a normal SIP header part as described above. For a bit more details and to look into the details, have a look to the dbg_sip_msg([log_level], [facility]) function in the debugger module. Best regards, Henning
