       eXosip is a GPL library that  extend  the  capability  of
       the oSIP library. It aims  to  implement  a  simple  high
       layer API to control SIP (rfc3261) for sessions establishements
       and common extensions.

       This eXtended library should  provide  an API for call management,
       messaging, presence features and everything you need with SIP.

       It's flexible, interoperable, stable and portable!
