# The AVP Module

## Admin Guide

### Overview

This module contains several functions that can be used to manipulate the contents of AVPs (Attribute-Value pairs). The AVPs are variables attached to the SIP message being processed. Each variable has its name and value. AVPs can be used to store arbitrary data or as a means of inter-module communication.

You may also want to check the avpops module which is more flexible and contains more functions. In future &kamailio; releases the avp module will be probably deprecated in favor of avpops module.
