SIP Communicator is an audio/video Internet phone and instant messenger written in Java. It supports some of the most popular instant messaging and telephony protocols such as SIP, XMPP/Jabber (and hence GoogleTalk), AIM, ICQ, MSN, Yahoo! Messenger, IRC, Bonjour and still counting. SIP Communicator is based on the OSGi architecture using the Felix implementation from Apache. This makes it very extensible and particularly developer friendly.
Mi interessa il dominio applicativo e l’implementazione di OSGi mi incuriosisce.
