Generation can happen under Generate if missing and Overwrite tabs.

Generation format

Generation string should be either:

Examples

<sip:3701234567@myhost.sip> - simple static generation.
<sip:anonymous@anonymous.invalid> - simple static generation.
<sip:$fU@myhost.sip> - using Kamailio variable $fU to generate a header with the original value from SIP FROM header
