AVPs are an older concept that go back to a time before OpenSER had really generic database interfaces or endless ways to craft custom business logic, many variables facilities, etc. At this point, the only real difference between them is that $var()s only exist for the duration of the processing of a given SIP message in the config script. AVPs are transaction-persistent, so, for instance, if you set one in an initial request route, you can also access it in the onreply_route, which is often necessary to do CDR accounting, etc. Also, some modules still require use of AVPs. If you're pulling data out of SQL queries and using it immediately, in the course of processing the same SIP message, just use $var()s. -- Alex Balashov - Principal Evariste Systems LLC 260 Peachtree Street NW Suite 2200 Atlanta, GA 30303 Tel: +1-678-954-0670 Fax: +1-404-961-1892 Web: http://www.evaristesys.com/ _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
