VoIP Phone- Advanced Flexible Telephonic Technique Reduces Call Cost

VoIP stands for voice over internet protocol; VoIP phone is an advanced telephonic technique that is used to make calls through the internet and to transfer the voice to any internet user and any land-line phone as well. 

At present VoIP phones are used a lot as these are the best solutions among all the telephonic techniques available in the world. These phones are very advantageous and do not require a huge investment. VoIP phones always require a high-speed internet connection like broadband and VoIP hardware only. 

VoIP is increasing in its popularity because it allows the user to make long distance calls for free in some cases or at very cheap rates. VoIP provides quality services at low cost and also have some incredible features. It is also used as a business solution worldwide so gaining popularity in business as well. 

If any person do not want to purchase a VoIP phone, but still wants to make use of VoIP services, it can use it through its conventional phone. This can be done using techniques available like PBX gateway, etc. that enables any conventional phone to make VoIP based calls. Using this technique the installation cost is also reduced for the VoIP phone and it is a powerful tool for different organization available worldwide. 

There are a lot of advantages of VoIP phones that made it so popular and useful for everyone throughout the world.  Some of the advantages are listed below:

1.    The VoIP phones are available in the market at very low cost. The cost included in the installation is not so high and can be used in the same cost as any conventional phone.

2.    The call cost can be reduced to a large extent using VoIP phones. This is the main advantage of VoIP phone, enables the user to make long distance calls at affordable price and sometimes free calling is provided as well.

3.    There is no requirement of a huge investment to use VoIP as only internet connection and VoIP hardware is needed.

4.    The govt. does not charge too much tax for using VoIP phone as internet is used to make calls.

5.    VoIP provides some extra features as well like, call forwarding, caller ID, call waiting, 3 ways calling, etc.

6.    One more advantage of VoIP phone is that it provides flexibility, i.e. it can be used anywhere in the world and one can take this anywhere with him/her.

As we saw various features and advantages of VoIP so in short it can be concluded that VoIP phones are very useful and should be used to reduce the calling cost.

Voip H.323 Definition

H.323 standard is defined by the International Telecommunication Union (ITU), which states that the protocols to provide audio-visual communication sessions on packet switched network.

The H.323 standard addresses call signaling and control, multimedia transport and control, and bandwidth control for point-to-point and multi-point conferences.

It is widely implemented by voice and videoconferencing equipment manufacturers, is used within various Internet real-time applications such as VoIP, Video conferencing over IP.

H.323 is now considered to be the standard for interoperability in audio, video and data transmissions as well as Internet phone and voice-over-IP because it addresses call control and management for both point-to-point and multipoint conferences as well as gateway administration of media traffic, bandwidth and user participation.

What are H.323 Components?

Terminals

Terminals are the client endpoints on the LAN that provide real-time bidirectional multimedia communications. An H.323 terminal can either be a personal computer (PC) or a stand-alone device, running an H.323 stack and the multimedia applications.

It supports audio, video and data communications. H.323 specifies the modes of operation required for different audio, video and/or data terminals to work together.

H.323 terminal plays a key role in IP-telephony services, and is the dominant standard of the next generation of Internet phones, audio conferencing terminals, and video conferencing technologies.

Gateways

A gateway connects two or more networks. An H.323 gateway provides connectivity between an H.323 network and a non-H.323 network.

For example, a gateway can connect and provide communication between an H.323 terminal and TDM networks (Time Division Multiplexing networks include all switched telephony networks, e.g., PBX, public switched telephone network [PSTN]).

The connectivity of dissimilar networks is achieved by translating protocols for call setup and release, converting media formats between different networks, and transferring information between the networks connected by the gateway.

For example, in the case of video conferencing a gateway may be required to call H.323 end point or VC in remote site and also to call a VC in remote end point on ISDN.  Basically gateways convert TDM traffic to IP packets.

Gatekeepers

The gatekeeper is the most important H.323 components. The gatekeeper's primary job is to act as the central point for all calls within its zone and provide call control services for registered H.323 endpoints.

Basic function of the gatekeeper is address translation, Calls originating within an H.323 network may use an alias to address the destination terminal. Calls originating outside the H.323 network and received by a gateway may use an E.164 telephone number to address the destination terminal.

The gatekeeper must be able to translate the alias or the E.164 telephone number into the network address for the destination terminal. The destination endpoint can be reached using the network address on the H.323 network. The translation is done using a translation table that is updated with Registration messages.

For example in Voice over IP which is driving voice traffic over IP network, we dial the extension number of the remote IP phone. IP network only handles IP not decimal numbers, because we cannot remember IP address of remote equipment we are dialing by number.

This conversion of decimal numbers to IP address and IP address to decimal number is done by gatekeeper. Besides these function gatekeeper also does Admission Control, Bandwidth Control, and Zone Management.

Using VoIP Termination in Business - Move Ahead

VoIP offers a slew of advantages to organizations, making the technology a hot favorite in business circles and helping them condition their network according to the demands of today's business needs. However, they need to hire the right VoIP service provider to attain their objectives.

VoIP has turned over the predictions of many a communication industry pundit head on who initially put forth the view that it will never become the front line mode of communication. Today, all industry sectors are gradually moving to business VoIP from the conventional PSTN (Public Switch Telephony Network) system. The shift has taken its time, but it is decisive.

VoIP based communication not just helps the businesses bring their telephony bills down, but also improves the way they function in the today's competitive scenario. It offers a slew of advantages to organizations, making the technology a hot favorite in business circles. It helps them condition their network according to the demands of today's business needs. An organization which lags behind in implementing the technology finds pulling itself hard in the rat race with the competitors.

VoIP enables features such as Instant Chatting in accelerating business cycles and promote collaborative team culture. Many a time, people prefer Instant Messaging to phone. Web based conferencing is another mode of communication powered by VoIP. Conferences have become an integral part of any business whether it is big or small. It offers the option of video conference with a group of people located all across the world, thus negating any need to fly across thousands of miles just to attend a business meeting.

Conventional PSTN networks cannot support such modes of communication. Additionally, with VoIP technology, users can opt for DID numbers that are ideal for organizations which are operating from different countries. It gets them to get international phone calls from overseas customers without their customers being aware of the fact as they are charged locally for it. The service is particularly beneficial for call centers as they need to provide customer service to people residing in other countries.

'Click to Call' option provided on several websites is also an example of VoIP powered services. VoIP call termination integrates the Internet with the phone call enabling the system. It shows how the technology merges voice and data networks. It enables business organizations to immediately connect to their clients. It also helps in raising customer satisfaction, which is something every business strives for.

Business houses have emerged as the final winner, thanks to the evolution of VoIP. However, for reaping the benefits, subscription to a VoIP service provider is necessary. You can subscribe to retail VoIP service providers who are themselves associated with wholesale VoIP carrier services. While a retail operator will be providing services to the end customers, it is the wholesale provider who provides the network infrastructure, software and technical team which makes the operations possible.

A robust VoIP network will ensure excellent technical operations, flawless exchange of data and non-interrupted service availability. Their technicians keep constant tab on the network and do the troubleshooting if required. In fact, quality of a retail operator depends of the wholesale VoIP operator behind it. If a retailer is backed by a reputable wholesale carrier, you can expect that he will be providing reliable services.

Traffic Partition For VoIP

IP telephony is a method of revising voice signals into digital IP packets and sending it through cyberspace to the final destination. Bandwidth partitioning for digital packets can be done dynamically. As users get active in traffic class, sub-partitions are created on the fly.

Everything has been changing in the Telecommunications industry in the past few years except one – Innovation. It has enforced conceptualization and implementation of ideas, one after the other. Successful implementation of one idea has led to the advantageous enforcement of another. The trend continues and who knows what we are going to see in future.

IP Telephony is one of the big ideas that have left a huge imprint in the industry. Popularly known as VoIP (Voice over Internet Protocol), it is a method of revising voice signals into digital IP packets and sending it through cyberspace to the final destination. A cost effective method of communication, VoIP technology is fast advancing. As it runs on server, it can be integrated with other applications, bringing in a host of other lucrative benefits.

Digital VoIP packets, sent via the Internet, require a certain amount of bandwidth in order for the transmission quality to be acceptable. Traffic partition for the VoIP class manages the aggregate traffic and the concurrent flows for the class. The partition is combined with a rate policy which defines a minimum rate for each flow. This ensures that VoIP always has enough bandwidth to support the multiple flows during a session. In absence of this reserved chunk of bandwidth, the conversation would be choppy.

Bandwidth can be assigned to digital packets dynamically. As users get active in traffic class, sub-partitions are created on the fly. This technology allows service providers the ensure for users a minimum amount of bandwidth at all times. This strategy is efficient when a small number of users will be active in any given time period. For instance, a service provider has 30,000 customers with a couple of thousand users logged on at a given time. With dynamic partition technology, subpartitions are automatically created for users as they log on. To accommodate new users when the upper limit is reached, the older non-active subpartition is removed releasing the bandwidth for active users.

You can also create static partitions. This kind of partition allows an aggregate traffic class to use a defined amount of bandwidth. Static partition ensures a specific amount of bandwidth for every digital packet and limits traffic to the same level. There is one more option called a burstable partition. It allows an aggregate traffic class to use a defined amount of bandwidth, and to access additional unused bandwidth, if required.

All partitions are hierarchical, which means that partitions can contain subpartitions. The approach enables application management for multiple groups, which can be controlled as a whole. For instance, a service provider can allocate different amounts of bandwidth for a particular application to various user groups. The basic concept for hierarchical partitions is that child partition minimums are limited to the parent partition. When the sum of the child partitions exceeds the minimum size of the parent partition, the child partitions are scaled proportionately.

For information regarding how to switch partitions, it is advisable to consult a VoIP technology expert. They have expertise in Hosted / Partitioned Softswitch technology, well versed with VoIP interconnection of gateways and switching.

VoIP may finally be on firm ground - Voip CALLS

People often look towards America to gain a litmus test of how an industry is progressing.  The US folks seem to be pretty good at taking the temperature of an industry or sector and making some assumptions around its likely success and future.  The Pew Research Center's Internet & American Life Project recently reported that almost one-quarter of Internet-using American adults have made telephone calls on the Internet via a service such as Skype, Vonage or MO-Call. The figure showed sharp increase over the last time Pew polled people on this question though this year was the first time Pew worded the question to offer Skype [sic] as an example of such a service.

What can VMNO take away from this latest comment on the health of VoIP?  The first lesson is VoIP is now being defined by the leading and well-known Brands.  This is certainly good news if you are one of the well funded VoIP companies spending some advertising dollars on having your Brand as a recognized verb around your technology. The prize is there for those that execute the technology well and spend some money in support of a growing global opportunity.

The second lesson may be that as a global demographic we are now ready to absorb this new way of calling.  Over the last couple of years we have all endured a financial crisis that affected us all.  We are now interested in the measure of cost/utility and wanting more for less. Alternative calling (VoIP) does this very well.

The third lesson and perhaps the greatest indicator of a moving continuum is the interest around Internet triggered calling, and web based communication generally.  Providing services around this new paradigm demonstrates a willingness and competency to support the ‘socialness' of the Internet.  The web has always been social, it is this by design.  Communication in 2011 must be interactive if it is to be sought out and used.  So what is interactive communication?  It is that part of the communication that adds intelligence to the thread.  That means that VoIP providers can support social networks and provide these portals with telephony and communication services around their interests and content.

The final lesson just may be that the incumbent mobile network operators, with all their combined financial power are just no match for a world of converging technology and converging competitive landscape where once friendly companions are now aggressive combatants

Is Business Voip Service Right For My Business?

Business VoIP services are already being hailed as the rightful successors to the traditional phone services. Many large enterprises have already integrated VoIP into their networks and with more sophisticated, affordable VoIP solutions in the market, small and medium businesses too are planning to start using business VoIP phones. This is probably the best time for any organization to take a look at the costs and benefits of business VoIP service and determine if it is right for them.

All that’s good with a business VoIP phone….

The most well-known and compelling reason for most businesses to consider VoIP is cost savings. A business VoIP service saves costs for a company on local calls and long-distance calls, which include both domestic and international calls. In particular if the company has many branches, within the country or overseas, then it makes a lot of business sense to go in for a VoIP solution as calls to and from the same provider are often free – similar to cell phone plans.

Other than cost-savings, business VoIP service offers many sophisticated value-added services which make it attractive. For example, a business VoIP phone service does not depend on the location. Whether you are calling an employee in an office a few thousand miles away or a local client, with a business VoIP phone, no extra cables are needed which means there are no extra costs. Also, you can carry your business VoIP phone number with you when you travel. No wonder it is called a virtual number! Where a Wi-Fi network is available, you could log into it and use your business VoIP service to start making and receiving phone calls. The same facility could be extended to mobile phones, which could use the VoIP network to make calls instead of standard mobile operators.

The biggest advantage of business VoIP service over traditional phone services is the complete integrated communications solution that it offers. With a business VoIP phone, it is possible to – make cheap domestic and international voice calls; take advantage of both audio and video conferencing; have features like call forwarding and call waiting; have voice messages and fax messages sent to your email address – and much more.

What’s not so good with a business VoIP phone…

While a business may benefit considerably with the cost-savings and additional features that a business VoIP phone service offers, there are certain cost factors, which need to be taken into account.

A business VoIP service is clearly dependent on power supply, implying that if there is no power, you will not be able to make or receive phone calls. This would mean you need a UPS to keep the business VoIP phone active during power outages and you would need a back-up PSTN line, just in case of emergencies.

Quality of voice in a business VoIP service had been an issue for some time, with complaints of echoes and jitters, etc. However, with VoIP solutions becoming more stable and mainstream now, you could get fairly good quality voice even on your business VoIP phone.

A converged network carrying both voice and data could raise issues of insufficient bandwidth, especially for small and medium business who typically have only one broadband line.

For any business, moving to a business VoIP phone service may be inevitable, but choosing a proper service provider will allow the company to seek features that will bring it immediate benefits, leaving a more comprehensive implementation for later.

Resource Box: Business VoIP can save a company thousands of dollars a year, some report savings of up to 80%. For smaller businesses a look at the benefits of a Business VoIP solution helps to see the advantages this new technology enables.

How Voip Help us to make free calls or cheap calls worldwide ...

Voice over Internet Protocol (Voice over IP, VoIP) is one of a family of internet technologies, communication protocols, and transmission technologies for delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms frequently encountered and often used synonymously with VoIP are IP telephony, Internet telephony, voice over broadband (VoBB), broadband telephony, and broadband phone.

Internet telephony refers to communications services—voice, fax, SMS, and/or voice-messaging applications—that are transported via the Internet, rather than the public switched telephone network (PSTN). The steps involved in originating a VoIP telephone call are signaling and media channel setup, digitization of the analog voice signal, encoding, packetization, and transmission as Internet Protocol (IP) packets over a packet-switched network. On the receiving side, similar steps (usually in the reverse order) such as reception of the IP packets, decoding of the packets and digital-to-analog conversion reproduce the original voice stream.

VoIP systems employ session control protocols to control the set-up and tear-down of calls as well as audio codecs which encode speech allowing transmission over an IP network asdigital audio via an audio stream. The codec used is varied between different implementations of VoIP (and often a range of codecs are used); some implementations rely on narrow band and compressed speech, while others support high fidelity stereo codecs.
