Page3 Project Overview: Reduce Communication Costs While Increasing AccessibilityandFreedom to work anytime, anywhere, on any device With today s diverse workforce, communication solutions must conform to the needs of individuals and organizations, not the other way around. Whether it s desk workers who need to be able to use their phone extension from a board room or sit at a different desk with a different phone every day, to mobile workers who need their work phone extension tied to their cellular phone, or even home-based or remote employees who need a full in-office experience regardless of where they are in the world, users demand the same feature-rich communications experience they have in the office, no matter where they are or what device they are using. In the office, at home, or on the go, IP Telephony mobility solutions help workers in organizations all kinds to be innovative and productive. Objective: In today s high-tech world connectivity to networks is extremely important for organizations to survive. IP Telephony mobility service facility gives PABX users the freedom to attend to office calls irrespective of their geographic location, and independently of their telephony device. Our mobility solution makes it easy for our workforce to communicate on the devices from any location (office, home, hotspots), and on any network (Wi-Fi, 3G/4G, WiMAX, CDMA and GSM Technology), they can access a full suite of mobile unified communications. Mobility extension is a unique function that turns a mobile into IP PABX extension and thus frees the user from the office. This solution is maintenance free and at very low running cost due to its intelligent call routing system. Your IP Telephony system can be utilized to link extensions with smartphones and user can easily contact you using a single number, whether you are inside or outside of the office. If you re traveling internationally, you can use Wi-Fi calling to call back through your IP Telephony Systems. Connect to a Wi-Fi network wherever you are and use Wi-Fi calling to place calls as if you were in the US, Canada, UK etc. You won t be charged international roaming fees or international calling rates. Stay in touch with people back home without having to worry about getting a large cell phone bill after you return from your trip. If your mobile is turned off or is in an area where there is no mobile coverage, and you cannot answer the call, the voice mail system can automatically answer and record the caller's message. Mobility Extension can increase employee mobility and organization's operational efficiency, productivity and enhance service by providing un-hindered access to wireless telephony.
Page4 Findings: On the basis of our observation we have found that most of the officials are using smartphones and brings their own mobile or laptop in your office premise. We can utilize their mobile phone as an IP PABX Extension inside the office and outside the office or global. With the help of your strong Wi- Fi, LAN, Branch to Branch Network and GSM technology, we can provide smoother Voice over Wi-Fi calling and Voice Mail services. Initial prototype deployment Initial prototypes and proof of concept deployment is being done by the maney corporate office and university. Understanding MAC Authentication: Each smartphones and Laptob has wireless network interface card (WNIC) used by a wireless client and has a unique media access control (MAC) address. For security point of view, all smartphone and protabled devices must be registrated in your Authentication and Authorization system. MAC authentication can be used and only method of client authentication and accessing the IP Telephony systems. Advantages of Wi-Fi Calling: Being able to call using a Wi-Fi network has many advantages, including improved reception and saving money. Systems Design & Protocols: UNIX Operating System Soft Switching SS7 signaling transfer points (STPs) H.323 Session Initiation Protocol (SIP) Session Description Protocol (SDP) Secure Real-time Transport Protocol (SRTP) Q.931 protocol IEEE 802.11a/b/g/n ITU Standards
Page5 Benefits of WiFi/Cell Architecture Telecommunications costs are lowered without changing employee habits Calls from cell phones are routed to the PBX Higher employee availability Extension rings cell when in Wi-Fi/Cellular Internet range Lower radiation for calls within Wi-Fi range No cellular transmission Improved functionality All PBX features (conference, recordings, etc.) available to cell phone
Page6 IP-PBX: Greater Access, Lower Costs Place/receive calls via cell/soft phone, no matter where located Auto forward incoming calls to mobile user Capitalize on Wi-Fi access where available to save costs and minimize health hazard Utilize Cellular Internet when Wi-Fi is not available Provide cell/soft phone users with full and direct access to IP-PBX functions Easy to use Project Implementation: No additional cost
Page7 Conclusion We, Optimal Technology offer integration of voice, video, data, and mobile communications on an open, distributed IP architecture that helps significantly reduce the complexity and costs typically associated with other solutions. The feature-rich UC system offers the lowest total cost of ownership (TCO) and the highest customer satisfaction in the industry, in part because it is easy to deploy, manage, scale and use.
