A.1 Obtaining the JAIN SIP and JAIN SDP Libraries

The NIST implementation of JAIN SIP and JAIN SDP can be obtained from https://jain-sip.dev.java.net. However, we also need other support libraries in order for JAIN SIP and JAIN SDP to work properly. So the best way to get all the needed libraries in just one shot is to download them from the SIP-communicator web page: http://sip-communicator.org. The sip-communicator project is an open-source initiative to build a fully featured and complex audio/video Internet phone and instant messenger. The sip-communicator project also uses JAIN SIP. After having understood the practices in this book, we encourage readers to take a look at the source code in the sip-communicator project. In order to download the JAIN SIP and SDP libraries, we have to download the whole project first, and then go to the lib folder and obtain the following jar files:

• JainSipApi1.2.jar and JainSipRi.1.2.jar (JAIN SIP libraries)

• nist-sdp-1.0.jar (JAIN SDP library)

• concurrent.jar, log4j-1.2.8.jar, jakarta-regexp-1.3.jar, and junit-3.8.1.jar (support libraries)
