This page provides a starting point for finding information about SIP applications, which are Java programs that use at least one Session Initiation Protocol (SIP) servlet written to the JSR 116 specification.
SIP is used to establish, modify, and terminate multimedia IP sessions including IP telephony, presence, and instant messaging.
You can apply digest authentication and Trust Association Interceptor (TAI) for a SIP application by applying Lightweight Directory Access Protocol (LDAP) security to the application.
