BioCluster is a peer-to-peer clustering platform for Asterisk, the open source PBX, which allows Asterisk to be used as a full carrier-grade telephony solution. It is meant to be installed on several machines together with Asterisk, turning them into a VoIP cluster. While the BioCluster peer-to-peer protocol was initially designed to cater to Asterisk-based clustering solutions, the BioCluster framework is capable of being extended to support various forms of normally unclustered devices or software packages.
BtFree is a library for creating client-server applications that communicate over a Bluetooth connection. You can use it in your MIDP application or in a Java application that uses an implementation of JSR82. It allows you to create applications with client-server interaction easily, avoiding the need to know JSR82 and the problems related.

SipUnit provides a class library that allows software developers to create automated unit tests for SIP applications. Session Initiation Protocol (SIP) is widely used for providing telephone services over the Internet. SipUnit extends the JUnit framework to incorporate SIP-specific assertions, and it provides a high-level API for performing the SIP operations needed to interact with or invoke a test target. A test program using the SipUnit API is written in Java and acts as a network element that sends/receives SIP requests and responses.
