What is Asterisk?

Asterisk is an open source framework for building communications applications. Asterisk turns an

ordinary computer into a communications server. Asterisk powers IP PBX systems, VoIP gateways,

conference servers and other custom solutions. It is used by small businesses, large businesses, call

centers, carriers and government agencies, worldwide. Asterisk is free and open source. Asterisk is

sponsored by Digium.

Today, there are more than one million Asterisk-based communications systems in use, in more than

170 countries. Asterisk is used by almost the entire Fortune 1000 list of customers. Most often deployed

by system integrators and developers, Asterisk can become the basis for a complete business phone

system, or used to enhance or extend an existing system, or to bridge a gap between systems.

Discover the Power of Asterisk:

Build Voice, Video and Text Applications Easily with Asterisk, The World's Most Widely Adopted

Open Source Communications Software Development Framework. Asterisk is an open source

framework for developing state-of-the-art communications applications. Asterisk includes hundreds of

pre-built components that handle the complex, low-level details of voice, video, and text

communications. Developers use Asterisk to create custom communications solutions and to build

innovative communications products. Discover how Asterisk can power your next-generation

communications deployment.

Digium: The Gold Standard in Asterisk Hardware:

Digium's Asterisk hardware extends the power of Asterisk to the Public Switched Telephone Network

(PSTN) and beyond. Digium is the leading manufacturer of analog and digital interface cards, voice

compression modules, redundancy solutions, and IP media gateways for use with the Asterisk open

Workshop 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.


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 (POC)” deployment is being done by the many corporate office

and university campus.

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

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

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
