1. Overview

This module provides the possibility to print user formatted log or
debug messages from Kamailio scripts, similar to the printf function. A
C-style printf specifier is replaced with a part of the SIP request or
other variables from system. Section 2, "Implemented Specifiers" shows
what can be printed out.

2. Implemented Specifiers

In the xlog function, you use pseudo-variables, that are a part of
Kamailio core and are used by other modules as well (e.g., avpops in
the function avp_printf())

The most important changes from earlier versions of Kamailio are:
* - '%' has been replaced by '$'
* - to print a header, use now $hdr(header_name[index]) instead of
%{header_name[index]}
* - to print an AVP, use now $avp([si]:avp_id[index]) instead of
%{[si]:avp_id[index]} or $avp([$avp_alias[index]) instead of
%{[$avp_alias[index]}

The full list of available pseudo-variables in Kamailio is available
at: http://kamailio.org/wiki/
