Voip - Internet Phone Service.

Making Voice over Internet Protocol calls over the Internet is very simple and really is an advantageous stand-in to conventional landline telephones or mobile phones. It is not a new concept for internet users and was not much used, as VoIP required broadband Internet and broadband is been increasingly used just starting form few years ago and has is becoming a prevalent activity among broadband users.

Why should you use VoIP?

The imperative thing about VoIP is the reduced cost comparing to call cost made over conventional telephone. Calls made within VoIP users are free even in case of international calls because you already pay for your regular internet usage. You may not need any additional equipment for this but require a headphone.

In addition, voice over broadband of 1Mbps onwards offers you the fine quality, better than that of a landline telephone call. The voice quality is generally adequate even if it is an ISDN line or a dialup line.

How does VoIP work?

A mature internet user knows the complex usage of internet, typically sending/receiving emails, audio/video and software downloads are few out of it. Making phone calls over internet is one another use of the internet and it is by VoIP.

A headphone will work in place of a conventional telephone and the only difference is how the conversation is carried from and to in between. The outline is same, no matter what type of broadband you have, ADSL, cable, wireless or satellite broadband.

The most striking offer of VoIP is that you can make free international calls anytime, to anyone who is a VoIP user too. But it does stop here. Still if you want to use VoIP to call folks who are not VoIP featured, just go and have your gateway service that act as a bridge between VoIP user and the conventional telephone users.

By its basic nature, VoIP allows communication among VoIP users only and in general, this is adequate for many. But for those have VoIP and still want to call a conventional telephone user, can have the PSTN gateway services to connect and call a conventional telephone user. In such case, you can look for a VoIP phone in place of headphone.

VoIP Make Your Calls, Straight Forward

It is simple to call using VoIP. A widely used free phone or messaging software and a headphone will do this. Have them and install it to your broadband setup.

If you are habitual to call people who use different softwares from yours, you need mutli-software installation and most of them are available as free downloads. MSN Messenger, Yahoo Messenger and ICQ are few of these free softwares.

VoIP handsets and their adapters fairly replace your headphone, making your talking experience enjoyable and are generally called, IP phone. Dual-purpose phones for calling both VoIP as well as conventional phone user avoid the existence of two phones and this make your calling experience, imaginative.

Broadband users who make regular calls to other broadband users can pick VoIP for two factors, cost and comfort. For those who make a lot of long-distance and international calls particularly, overseas calls, VoIP nearly replace the regular telephone usage.

For business people, VoIP is a sensible alternative. Business users can benefit from significant saving on calls via VoIP. Business houses, operating from international locations can make extensive use of VoIP. What other than that of making calling to your customers and suppliers for free or at slashed rate is going to be your better business thought.

You can compare all major cheap broadband suppliers and get broadband offers if you shop around and earn cash from cash back from a reward site.

If you’ve decided to go with VoIP phone service, you might be confused as to which provider is best for your circumstances. Choosing a VoIP service provider is similar to choosing a carrier for your mobile phone. You will want to compare the options available to you as well as the prices.

The first thing to decide is what you want to use your phone for. If you are looking for a complete replacement for your regular phone service, you’ll want to check out the company and see what they offer in terms of cheap international calls and phone features. Some companies allow you to call certain areas of the world for free. Others charge you per minute. Most offer different packages that you can tailor to fit your needs. One of the biggest VoIP providers, Vonage, has a plan that gives you unlimited phone calls throughout the United States, Canada, Puerto Rico, France, Ireland, Spain, Italy and the UK. Of course, you might have a higher monthly bill than if you decided to pay for long distance as you use it. It all depends on your calling habits and where a majority of your calls will be.

You should also check for special promotions that the companies are offering. You can sometimes get a certain number of months for free, or a low introductory monthly cost. Some companies will give you the equipment you need for free or give you a thirty day money back guarantee. You should also see what type of features are included with your phone service. Many companies offer free call waiting, caller ID, or three way calling.

One thing to check for is the length of the contract you are expected to sign. You will often need to remain with the service for a year or more. If you cancel it prior to the year, you will need to pay a fee. Make sure you know the terms of your contract before signing.

If possible, you will want to talk to customers in your area and see what they think of the service. The quality of the calls can depend on your internet service provider and even the area you are located in. If you can try out the provider at a neighbor’s or friend’s house, this can give you an idea of how the calls will sound at your home. There are many sites online where consumers can leave a review regarding the quality of their VoIP service.

VoIP is an abbreviation for voice over Internet protocol. It is easy to confuse VoIP with broadband phone service. Though broadband phone service uses the voice over Internet protocol to send and receive phone calls, it is not actually VoIP. As of now, VoIP basically comes in three forms, PC-to-PC, PC-to-Phone, and Broadband telephone service.

You may have used the most common PC-to-PC or PC-to-phone VoIP services without even realizing it. Have you ever used Yahoo Messenger to call someones computer? If you have, you’ve used Yahoo’s free PC-to-PC VoIP service. Additionally, Yahoo Messenger allows you to call someones home telephone from your computer for a small fee. This is called PC-to-Phone VoIP.

Broadband phone service also uses VoIP but allows you to make and receive calls on your home telephone the same way you always have. While PC-to-Phone, and PC-to-PC only require a software download to use the service, you’ll need a broadband phone adaptor to be able to use your home telephone with VoIP. Once installed, broadband phone service is very much like a traditional land line with just a few exceptions.

Now we know VoIP is the means of transmitting voice data over the Internet, and PC-to-Phone, PC-to-PC, or broadband telephone are the VoIP hardware and software solutions for VoIP. Armed with that information, which is the cheapest solution in VoIP for you? Free VoIP is not always the cheapest solution in VoIP. Let me explain.

As mentioned before, PC-to-PC VoIP is often times free with Popular Instant Messenger clients such as Yahoo Messenger, MSN Messenger, and now, Google Talk. These messengers provide an excellent free service which allows you to talk to friends and family over long distances through your home computer and speakers or headset.

What if you need to call someones home telephone or business phone? That’s where PC-to-Phone Voip comes in. PC-to-Phone allows you to call a telephone from your computer. Though PC-to-Phone isn’t free it’s very cheap, sometimes around 1 cent per minute or less. Examples of Popular PC-to-Phone VoIP services are offered by Yahoo Messenger and Skype.

Broadband telephone service allows you to make and receive phone calls without the aid of you’re computer. Broadband telephone is hyper popular since it cuts out the telcos and dramatically reduces your phone bill. Some VoIP companies offer unlimited local plus long distance calling for a flat fee of less than 20 dollars per month.

As with anything else, the cheapest solution for VoIP is going to be determined by your usage of the service. If using your computer to talk with your contacts does not bother you, by all means use PC-to-PC or PC-to-Phone. If you want to reduce your phone bill, and enjoy the convenience of talking on a normal phone, broadband telephone is going to be the cheapest solution in VoIP.

The world of telephony is undergoing a revolution. Mobile phones are everywhere in both developed and underdeveloped countries and now another great development is technology that enables anyone to make phone calls over the Internet for free or for a fraction of the normal price.

Calling over the Internet is done with a process known as VOIP , which stands for Voice Over Internet Protocol. In many applications of VOIP, such as the popular Skype service, Internet phone calls are made using a computer. A user of this type of VOIP service must connect to the Internet and make phone calls using a microphone, or attached headset. It is possible to call users on another computer, or, for a fee, to make calls to landlines or mobile phones.

While computer to computer calling and computer to landline calling has become popular, a new application makes it possible for consumers to make long distance calls over the Internet, using their existing land lines or mobile phones. The service, provided by a European-based company known as Jajah, works by making local phone calls at both ends of the connection and then connecting the two parties over the Internet, thus by-passing the long distance charges of the conventional telephone companies.

The users of the Jajah service do not have to call using their computer or purchase extra equipment. They can make calls using either their landline or their mobile phone. Calls between members are free of charge, and other calls are billed at rates that are substantially lower than conventional long distance charges.

For those Jajah users who want to use their computer directly, they can take advantage of a growing list of services including conference calls, call scheduling and text messaging. While all of these computer based services are similar to those offered by Skype, Yahoo and other VOIP applications, Jajah’s big selling point is that its primary service allows consumers to make phone calls using their normal telephone apparatus and without changing their normal calling behavior.

Another attractive feature of Jajah is that it has an affiliate system. Affiliates can place banner and buttons on their website and earn a portion of the revenue that Jajah gets when web visitors sign up and use the service. Some successful affiliates claim to have made thousands of dollars through their participation in the program.

The world is becoming smaller and smaller thanks to the availability of cheap mobile and Internet calling services, and this trend will only accelerate in the years ahead.

I have been hearing and reading about lots of complaining concerning the voice quality of a VoIP connection….both residential and business Is this real or memorex (so to speak). Just what are the REAL issues…and where may we (especially businesses) be headed with the maturation of VoIP?

The issue is still that our IP networks are packet based. This is efficient for moving data, but not so good for time and sequence sensitive traffic.

Over private networks, we can adjust the communications elements for session versus packet centric performance. We make sure we have sufficient bandwidth to allow a smooth stream of session traffic (VoIP for example), we adjust prioritization so that session traffic has priority, we change our balancing and routing to insure sessions follow a consistent symmetrical route. The result is a less efficient use of our bandwidth capacity, but a higher quality session for the users. In short, we move away from the purely packet delivery focus and towards a channel like network.

Over the Internet, we lose the ability to optimize our session traffic. The Internet is by design application neutral. The focus is on packet delivery, and each packet is as important as every other packet. At each step in the communications path, the devices are tuned to receive a packet, determine which port to send it out next, and move it on its way. Load balancing across multiple paths, each packet to a given destination may take a unique route. The criteria for success is the delivery of packets error free.

So what is likely to happen? I expect prioritization of session traffic over the carrier networks. They will implement it first for their own services, and the cost of doing so will be recovered from that service revenue. It will be available to individuals, companies, and competing service providers as a premium service. After all, it is a level of delivery above what simple Internet access promises. To work, the carriers will have to agree on respecting each others prioritization when traffic moves from one carrier to another. This will probably be no different than their current method of carrying each others traffic from business sense, and the engineers will quickly work out the technical aspects. The VoIP service companies will scream that this isn’t fair, that their service is simply using bandwidth paid for by their customers’ access fees. However, session prioritization is not what their customers’ have contracted for, so their complaints will be ignored. A new level of access will become common - possibly called Voice Assured or something along that line.

At some point, either a new startup carrier or an existing carrier will decide to market session priority as part of their standard level of service. If sufficient customers switch to get this, the other carriers will follow suit. By that time, most of the networks will have become session prioritized as the standard build.

Big iron will not benefit from all of this.

Some session service providers will lose out to the carriers because their business model relies on the performance of a competitor. Some will step up and pay for session priority so that their customers do not. If they can survive with the reduced margins until session priority becomes the norm, they will retain their customer base.

(Q)Has anyone experienced poor call quality using VoIP?

Yes - of course most people have knowingly or unknowingly. VoIP traffic in all methods of delivery- Skype, Vonage, Cable, IP-PBXs, Peer-2-Peer, softswitches and COs… have varying degrees of voice quality issues in their experiences with VoIP. At least for now.

(Q)Is this a case of poor equipment, poor software, bad connections, or what?

This is a very broad issue. Too many people expect to “just plug it in” and it’s going to work- whatever “it” is defined as. The same is true about VoIP due to marketing, misfires, bad judgment, and inexperience.

There are many other reasons too - DSPs which are improving (Fact), software gets fatter which patches the known existing issues and maybe creating a few new unknowns still (My belief), connections- a few in the cables, connectors themselves but everything is relevent to what is defined as VoIP which is just a protocol- what about all those other things to access, control, and transport those packets?

Then - keep in mind that a significant majority of “telephone lines” are copper, TDM based. Longer loops have boosted loop current levels and mixed with IP — you get echo.

The “list” of issues or causes and effects is just mind boggling. It’s not simple or black and white - short answer is “it depends.”

Once VoIP can meet those expectations of “just plug it in” then we will in doubt be in a new world of telecom. It’s a journey and it will be an adventure for those that tough it out. It will be interesting to see and experience how it all plays out.

(Q)Do you think that less than toll quality voice will be a limit to the growth of VoIP?

No. Less than toll quality isn’t a VoIP metric for enterprise or carriers (Big Iron) or the softswitch world either. VoIP as a whole - is improving- at least so says the media. Call quality is moving away from what we do for example with software and an appliance to watch voice packets, equipment, and other things… to embedded monitoring call quality within the software itself reporting back across the network. This is significant in when it becomes the norm— then less expensive solutions to monitor, packet shape, and direct voice packets to their final destinations on time will notably change quality, MOS scores, etc. Who can afford the existing tools other than Big Iron and L-Enterprise ?

(Q)If poor voice quality continues can this cause a backlash against VoIP and a return to Big Iron for some companies?

Not likely. Too much is already invested and proven in the way of the carriers successfully delivery VoIP traffic without the end-user knowing they are in fact on a VoIP segment or call. Ethernet Layer 2 provides a slightly cheaper method of delivery over TDM and since cost is always a factor and as “techniques” improve so will delivery. It isn’t likely that a “pull out” will occur.

(Q)What can be done to raise VoIP voice quality to toll grade?

It depends upon which audience is addressed. From where I sit:

1) Training - Certification - Field Experience by those implementing VoIP;

2) Metrics that measure not just MOS but the actual voice packets for jitter, latency, etc and then accountability in the missions of those making the decisions- did we achieve our objective and what were the true costs in doing so and how did it impact us?

3) Timing - hardware isn’t getting worse, it’s getting better. (That’s a fact) The industry is in a learning curve- one that’s not going to become stagnant because deliverying VoIP in any form factor is challenging- it’s not for those faint of heart. (Implementers)

4) User Expectations - this is one of the greatest failures not just in VoIP but delivery of any telecom / IT service or solution. The expectations are not set and there is a consistent failure of “the meeting of the minds.”

5) Benchmarking vs. Hook-Line-Sinker - instead of ramping an entire effort for VoIP cutovers - organizations need to set some bench marking in place first. The temptation to go big vs small because the leaders within the organization need to score a big hit (cost savings).

6) QoS, access, transport, infrastructure - these all apply to any user of VoIP.

Before jumping in, catch up and get into more specifics about what is wanted, methods of delivery, metrics, how VoIP is planned before inking a deal or making a change with someone promising them something better, faster, cheaper - as with anything.

VoIP is here to stay. Sink, swim, or paddle - it’s rewarding, it’s a beast to manage, challenging and very rewarding for those who are prepared.

VoIP security has been called in question recently, though there is little evidence to indicate that VoIP security is any less than conventional telephony systems.

VoIP voice data is transmitted via a packet-switched data network using IP. VoIP systems can carry a significant higher number of calls, and very much faster, than traditional PSTN networks due to compression of the voice packets, modern broadband technology and a number of other gateway developments which have reduced the previous packet delivery problems to an extent that the protocol is now a viable mainstream telephony solution to most business needs.

VoIP security should therefore be shown to be at least as effective as that of traditional telephone systems.

There is actually very little difference between VoIP security and that required for any other type of data transmission system. Look on it the same as you do your email system. The same as your office LAN if you have one. You probably have a system in operation whereby only authorized personnel can use certain aspects of the network. VoIP security can, and do, use the same techniques.

However, having said that, let’s have a look at potential weak points in VoIP security that budding hackers may see as good points of attack.

IP PBX CALL MANAGEMENT BOXES

PBX stands for Private Branch Exchange, and is piece of software running on a server. It’s function is to deal with all the switches and connections involved in the telephone system. These can be attacked by hackers or viruses which could compromise sensitive data. VoIP security systems are designed with this risk in mind.

PBX equipment should be placed behind firewalls, locked down and regularly monitored for unwarranted intrusions using intrusion-detection software. It is also possible to put the server in a different domain from the rest of the system, making it much more difficult for intruders to reach. PBX security is a basic aspect of VoIP security systems

GATEWAYS AND DATA PACKETS

The gateway’s job is to convert voice to data packets, transmit them then receive and convert the packets back into voice. These are a potential VoIP security risk in that thy can be hacked into unless there is an access-control system in place to prevent unauthorized people from accessing the system. VoIP calls should only be permitted to specific people, and most good VoIP security systems allow only authorized user to operate VoIP systems under password control.

The data packets themselves can be hacked into using data-sniffing techniques. This can be a serious VoIP security risk and packet sniffers, as they are often called, capture binary data passing through your network and can reroute it to a computer on another network for decoding into a readable form. In order to do this, the ‘sniffers’ has to be on the same network wire as the packet is using to reach its destination. The problem in installing an effective VoIP security system is that there is usually a lot of information passing at any one time, and the hacker has a higher probability of getting useful information than from a conventional telephone system.

Encrypting VoIP traffic and routing it through a virtual private network would reduce the VoIP security risk, and most corporate systems have multiple encryption layers for external messages. Internal security could be improved by running internal VoIP messages through this corporate network. Small businesses should seek the advice of their supplier, or of a security expert if they feel that they may be subject to such attacks.

However, VoIP security advisors can point small to medium companies in the right direction. Corporate VoIP security is generally not so much problem in that it is normally contracted out to expert advisers.

In the final analysis, however, there are no real differences between VoIP security and the normal security concerns associated with any data network service, such as normal office internet and email LANs. The security firewalls and restricted access to use, common on these systems, should suffice to deal with VoIP security

Though PC-to-Phone isn’t free it’s very cheap, sometimes around 1 cent per minute or less. Examples of Popular PC-to-Phone VoIP services are offered by Yahoo Messenger and Skype.

Broadband telephone service allows you to make and receive phone calls without the aid of you’re computer. Broadband telephone is hyper popular since it cuts out the telcos and dramatically reduces your phone bill. Some VoIP companies offer unlimited local plus long distance calling for a flat fee of less than 20 dollars per month.

If using your computer to talk with your contacts does not bother you, by all means use PC-to-PC or PC-to-Phone. If you want to reduce your phone bill, and enjoy the convenience of talking on a normal phone, broadband telephone is going to be the cheapest solution in VoIP.
