Dear Sir,
I take great pleasure in submitting this report on the topic “Implementation of Soft Switch Application System and LOGICAL TOPOLOGY IMPLEMENTATION PLAN for IGW” which was assigned to me as a requirement of the Bachelor Program in Electronics and Telecommunications Engineering at North South University.

While working with the Soft switch (Vos3000) and developing website for IGW (International Gateway Companies) under R&D department I learnt a lot about how to setup vos3000, and about IGW companies’ route, plan and traffic. During my internship period I worked closely with the specialists at R&D department. I was the team leader of the project of IGWBD safe business for telecom sector. I also learnt about how to Design the IGW IP and Vlan working procedure . I worked in a team and sometimes there was a lot of pressure as we had to achieve targets every day at Bangla Tel Company. I learnt how to work in a team and deal with actual work pressure.

I sincerely hope you will be satisfied with my work at Bangla Tel, As it has been a valuable experience.

I would like to request you to accept my report and oblige thereby.

Sincerely yours

Rajib Das

For the Project we had to study about International Gateway, VOIP and we also gained practical knowledge on VOIP Soft Switch (Vos3000) checking connect analysis, current call and interrupt analysis. I have also met with Novotel and Mos5Tel Companies to ask for their co...
