The AVPops (AVP-operations) module implements a set of script functions which allow access and manipulation of user attribute-value pairs (AVPs, preferences) and pseudo-variables. AVPs are a powerful tool for implementing services/preferences per user/domain. With this module, they are usable directly from configuration script. The module implements functions for interfacing DB resources (loading/storing/removing), functions for swapping information between AVPs and SIP messages and a function for testing/checking the value of an AVP. If you just need a way to execute SQL statements in a Kamailio configuration script, please consider use the sqlops module instead. AVPs are persistent per SIP transaction, being available in "route", "branch_route" and "failure_route". A tutorial providing more information (detailed explanations and commented examples) can be found on the SIP-router web site.
