摘要：Most organizations concurrently maintain private Automatic Branch Exchange (PABX) and Local Area Network (LAN) for information interchange within their organization. This is obviously a waste of resources and avoidable duplication of communication systems. The existing LAN can be used as a communication backbone for the in house telephone operations with no extra cost and resources. In view of this, a portable and a platform independent Software-Based Cell Phone (SCP) was proposed for the existing LANs infrastructure in the organizations. The SPC is a telephony application with a user friendly interface which is capable of handling voice, video and text messages without compromising the Quality of Service (QoS) of the existing LAN.
