Landline/mobile bridge via internet

Abstract

In this graduation project , a cost effective and practical method of communication is proposed. The focus is on resolving the situation that is faced when the person you are trying to reach through the landline is not available to answer . it is common in the large companies to use the GSM ( global system for mobile communications) network to contact the mobile of the desired subscriber . despite the fact that GSM can do the job, but it is expensive. Instead , in our project , a free cost effective and more practical method of third party ( the system ) communication is suggested and discussed. This is briefly the coexist of landline connections to the mobile throw GSM system by the well known internet protocol (VOIP), which will enable the application of this concept even in the small scale of homes or small offices , schools and universities. We built our system using all the needed hardware components and software programs , and we created away to interface them with each other, to completely achieve the system objectives in efficient way.
