Hi all,
I'm glad to announce and to provide you the module I've done few months ago. It's based on libpurple, the library on bottom of pidgin (ex-gaim), and allow you to use all your non-SIP accounts (like MSN) mapped with your SIP URI. It was originally wrote for OpenSER 1.3.x, but I ported and tested it to latest Kamailio/OpenSIPS snapshots. Please refer to included README for more informations. I hope you'll enjoy it !
