VIRTUAL CALLING SERVICE

The ability to transmit and process voice over Internet protocol (VoIP) networks has important implications for technology users especially by the using Asterisk PBX. Many companies nowadays are rushing to bring different VoIP products to market with a wide variety of features. This project will focus on the introduction of VoIP and its implementation by the use of Asterisk PBX. Firstly, the abstract presents the project objective with some introductory theory about VOIP. Secondly, the project includes report on the viability of utilizing the Asterisk PBX as a foundation for conducting research performance studies for VoIP. Finally, the project is showing on live experimental studies of SIP voice traffic. The article experimentally studied the performance of voice calls initiated using SIP simulator for testing SIP protocol performance and found much more stability and accuracy using Asterisk PBX. The purpose is to suggest those VoIP technology attributes that best meet users’ needs. Asterisk, the open source PBX of choice is used to show that this is maturing fast and ready for main stream VoIP implementation.
