VoIPVoice over IPVoIP (voice over IP) is thetransmission of voice andmultimedia content over InternetProtocol (IP) networks. VoIP is nowa realistic solution for businesseslooking for an alternative totraditional telephone networksknown as Public SwitchedTelephone Networks(PSTN). VoIPcalls can be made phone-to-phone,computer-to-phone, or in otherways.White Paper - VoIP 3.
VoIP TECHGYANVoIP encapsulates audio via a codec into data packets, transmits them across anIP network and decapsulates them back into audio at the other end of theconnection. VoIP endpoints include applications running on mobile devices andPCs or dedicated desktop VoIP phones. VoIP endpoints typically use codecs, suchas G.711, this does transmit uncompressed packets, or G.729, which doescompressed packets which reduce bandwidth requirements. VoIP typicallysupports non-voice communications via the ITU T.38 protocol for sending faxesover VoIP.Once voice is encapsulated onto IP, it is typically transmitted via the real-timetransport protocol or through its encrypted variant, secure real-time transportprotocol. The Session Initiation Protocol (SIP) is most often used for signalingthat is necessary to create, maintain and end calls. Within enterprise or privatenetworks, quality of service is typically used to prioritize voice traffic overnon-latency-sensitive applications to ensure acceptable voice quality.VoIP system may include an IP-PBX to manage user phone numbers; gatewaysto connect networks and provide failover in the event of a network outage; andsession border controllers to provide security, call-policy management andinter operator network connections. A VoIP system can also includelocation-tracking databases for call routing and management platforms tocollect call-performance statistics for reactive and proactive voice-qualitymanagement.White Paper - VoIP 4.
BIG ADVANTAGES OF VoIPFOR SMALL/LARGE BUSINESSES1. Cheaper Outbound, Inbound, and Toll-FreeMinutesVoice over Internet Protocol, for all its amazing features, is best known for howcheap it is to make a call. The low prices are, in part, due to the fact that VoIP isbuilt upon the existing infrastructure of the internet, and because the voicedata is cheaper to send over internet protocol compared to the circuit-switchedPSTN. Calls that connect to SIP addresses rather than phone numbers arecheaper now. You can further add to your savings by tailoring your phoneservice to each division of your business.Certain buildings, such as warehouses, make mostly internal calls; otherbuildings, such as offices, make and receive many calls; a customer servicecenter primarily receives calls. Whatever combination of calling plan you wantCUG calls, inbound, outbound, toll-free, metered or unlimited plans, VoIPprovider can customize plan down to each individual phone, saving moneyevery month.White Paper - VoIP 5.
2. CUG Calls are Free and Easier to MakeCell phone networks have free calls between subscribers of their service.Business VoIP service providers are the same way, but business VoIP services aremade with features designed specifically for business. An IP-PBX connects notjust a building, but your entire company. You can have extensions with three ormore digits, so calling a colleague half a world away is as simple as pressingthree buttons. When you have hundreds of employees spread across the world,having your own internal network of free calling can save you tens, evenhundreds of thousands of rupees compared to the cost of older PBX systems.Business surveys have shown that at about half of organizations, coworkerscan’t reach each other at the first phone they call. Because VoIP is connected toyour computer, there is desktop software that lets you see if your coworkers areon the phone or not (a feature known as presence), and you can click their iconto call them, and you talk to them using your desk phone. If they are busy, thesame software lets you leave a message on their voicemail without disturbingtheir phone call, and lets you email or IM them. This adds up to moreproductivity, less down time, and more profit.White Paper - VoIP 6.
3. Get The Same Enterprise-Class Software, Butat a Lower PriceVoIP solutions are customized to the needs of each client. Whether you are acall center, a multi-faceted business with many different departments andspecialists, or a business that does a high number of online meetings andwebinars, hosted VoIP includes many features you need as standard, or as anaffordable add-on.Hosted VoIP includes many Fortune-500 company features at an everyday price.We can take advantage of the low price and hefty feature set of VoIP, including ACD call queues Auto attendant Call parking Conference call Dial by name directory Group ring Music on hold Voicemail transcriptionWHEN YOU HAVE HUNDREDS OF EMPLOYEES SPREADACROSS THE WORLD, HAVING YOUR OWN INTERNALNETWORK OF FREE CALLING CAN SAVE YOU TENS, EVENHUNDREDS OF THOUSANDS OF RUPEES COMPARED TOTHE COST OF OLDER PBX SYSTEMS.White Paper - VoIP 7.
4. New Technology - Better Sound QualityVoice over Internet Protocol is a continually evolving and improving technology.One aspect that is being continually developed is sound quality. Widebandaudio, also called HD Voice, extends the frequency range and doubles thesample rate of telephone audio, making it easier to distinguish betweensyllables in the higher range. Better sound quality makes for easiernegotiations, better business to business communications, and better filteringof background noise.5. International PresenceVoIP calls overseas are very cheap, to most of the world. But low internationalrates are just the beginning. All calls within your own network, includinginternational calls, are included with business VoIP plans. You can even use asmartphone or laptop to connect to VoIP network over a Wi-Fi hotspot, savingyou international roaming charges.But the truly remarkable thing about VoIP is telepresence. With telepresence,you can converse with your colleagues half a world away as if they were in thesame room with you.White Paper - VoIP 8.
6. New Tools to Aid in TimeManagementYour time and attention, and your employees’time and attention, is valuable. With VoIP, youhave a wealth of tools to help manage thattime.Call center programs, for instance, keep trackof how long callers are on hold for, how longconversations take, and even how oftenemployees take lunch or bathroom breaks.State-of-the-art software allows multiplecallers to jump past a queue and connectdirectly to available agents.CLICK AN EMAIL AND CALL THE PERSONTHAT SENT IT TO YOU. RECEIVE APHONE CALL AND HAVE A SCREEN POPUP WITH THE CALLER’S LASTOUTSTANDING BILL. WITH VOICE OVERINTERNET PROTOCOL, YOU, AND YOUREMPLOYEES, WILL HAVE ALL THE TOOLSYOU NEED TO GET THE MOST OUT OFYOUR BUSY WORKWEEK.White Paper - VoIP 9.
7. Take it With YouWith VoIP, employees are empoweredto work anywhere. Instead of buildinga new satellite office, and having topay for rent and utilities, you can havethem log in from any computer, or useany IP phone, and have themtelecommute. Your telecommutingemployees will use the same softwarethat your call centers use, but they canwork from home.Similarly, important business calls can be made from anywhere in the world. With VoIP,you can prevent incurring expensive roaming charges and instead connect smartphonesto your VoIP provider over any Wi-Fi hotspot.White Paper - VoIP 10.
