M4 PAI And RPID Header Generation

M4 can generate P-Asserted-Identity (PAI) and Remote-Party-ID (RPID) headers

Usage

Go to Users -> Connection Points, click EDIT on Connection Point. PAI/RPID Transformations are located under Termination Point Signaling Settings.

Generation can happen under Generate if missing and Overwrite tabs.

Generation format

Generation string should be either:

• a static string (the value of the RPID/PAI header)
• a string mixed with Kamailio variables

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 header with value from SIP FROM header
