Low Rate VoIP: The Real Score About It

Thursday, September 17th, 2009

It is not uncommon for people to look for low rate VoIP. In general, all forms of VoIP services are already cheaper than the usual telephone service. Since there are many VoIP providers however, service prices also tend to vary. Depending on several reasons and factors, some providers are really cheaper than others. Here are a couple of things you should know about low rates for VoIP.

Free VoIP Services

These days, nothing comes for free anymore. With VoIP becoming more popular, it is hard to imagine that anyone would offer it for free. There are however some instances when VoIP can be had for free. If you are looking for the lowest VoIP rate, nothing can go lower than free. Here are some points to consider about free VoIP services.

- Some providers may offer VoIP for free but only as part of a promo. The free service may not last for long so you should make sure to check the fine print before using VoIP with a provider.

- 100% free VoIP may also be offered by some providers but only for a limited number of places only. In some cases, they may limit the number of hours you can use the service. They may also limit the number of IP addresses you can send to.

- A number of small independent providers may offer free services with few limitations. These may be small companies though and they may not always offer the features that bigger companies offer. Voice quality may also no be as excellent.

Low Rate VoIP

Is free service for you? You may want to have some features that just aren’t available in free services. If this is the case, then you might just want to settle on paying for low rates. Again services, with low rates have a couple of considerations:

- Price isn’t the only indicator that should influence your decision. The lowest VoIP rates don’t always mean that you have a great deal. The low rates may be because a company is not yet well known. It may also be because they really don’t offer good services. Before signing up for VoIP providers with low rates, make sure that they have fairly tolerable services.

- Chances are, if you choose your features carefully, you’ll get lower rates. You may for example, not need 3-way call or redirect call features. If you want to have VoIP simply for making basic, personal and local calls, then you can pick the package with less features so you also pay less.

Checking Out a Comparison Site

Online Comparison – The best way to find the best VoIP rate deals is to go to comparison sites. Various sites rate, rank and review VoIP services. Depending on the site you are on, they may also provide the specific features of various VoIP providers.

It would be good if you picked a comparison site that actually really tests VoIP. Some sites may only offer reviews based on second hand information. An alternative would be to go to a site that has consumer reviews in it.

Finding a low rate VoIP may not be such an impossible feat. You do have to spend some time though, finding out if you really have a good deal on your hands.

The Beginner’s Guide To How DSL Works

Wednesday, July 29th, 2009

by Tammy Lawsone

Most DSL subscribers don’t know – and likely won’t care – how the technology works. That said, it’s worth spending a few minutes to explore the type of equipment involved and how it contributes to delivering fast internet access. Below, we’ll take a quick tour through the technology and follow the transmission of data as it makes its way from a server to your computer.

What Is POTS?

A digital subscriber line uses an antiquated infrastructure called POTS, an acronym for “Plain Old Telephone Service.” POTS sends and receives voice data through analog signals. These signals travel along the copper wires through a jumble of switches, transmitters, and other equipment. It does so at a frequency of 3400 Hertz.

The key that allows DSL to work on the same infrastructure as your telephone is that the 3400 Hertz frequency range is only what is available for voice data. In reality, the true range of frequencies available on the copper wire is far greater. The extra “space” is what supports the transmission of digital – or non-voice – data (i.e. web pages, video, etc.).

Frequencies And Channels

The digital information is transmitted through the DMT or CAP systems. If it goes through DMT (or, Discrete Multi-tone), the information is split into 247 different channels. If it goes through CAP (or, Carrierless Amplitude/Phase), the information is split across three different frequencies, depending upon the intent. One of those frequencies is specifically for voice data. Another is for moving packets from the customer to a server. The last of the three is allocated for packets traveling from a server to a customer’s computer.

Additional Equipment Needed

In order for DSL to work, the connection must have access to two more pieces of equipment. The first is the modem or transceiver. It is located at the customer’s residence and functions as the liaison between the user’s computer, or local area network, and the digital subscriber line.

The second piece of equipment is the digital subscriber line access multiplexer (more commonly called the DSLAM). The DSLAM is located at the provider’s central hub. Its function is to aggregate all of the signals produced or triggered by the provider’s customers into a single pipe. That pipe forms the online connection. The DSLAM can also perform the duties of a router as well as handle the assignment of IP addresses to customers.

The DSLAM represents the difference between a DSL connection and cable access. Even though it aggregates all customer data into one pipe, it maintains an exclusive connection for each. Contrast that to a cable connection in which the rate of data transmission is reduced each time a new user joins the network.

Even though DSL uses an older technological infrastructure, many subscribers consider the experience of using it superior to newer technologies.

Equipment Requirements at a Work Call Centre

Thursday, July 16th, 2009
by Amy Nutt

You will need to be prepared to invest quite a bit of money on getting the right equipment for establishing yourself as a work-at-home open source call centre assistant. It is also important to be wary about buying the right sort of equipment and high quality gear at that. The equipment needs to be built to a high standard and expected to last a decent amount of time, so automatically going with the cheapest options can often turn out to be a false economy.

The most expensive and also most important requirement is to have a computer. If you want to be on the move and have a little more flexibility with regards to where you work, then a laptop can be a great option. However, price-wise, desktops are still cheaper and are generally capable of more as well as being more upgradable. With computers as cheap as they are nowadays, this is not likely to be a particularly daunting investment considering all of the other things that you can use a computer for too. Since most people will already have an adequate computer system, this is unlikely to even be an issue.

The Internet connection required can be a slightly demanding requirement in some cases. For a call centre, you will need to have an adequate amount of bandwidth so you can use the Internet telephony / VoIP programs that you will need. This basically rules out any older 56k modem connections. Cable modem and DSL are generally adequate but bear in mind, any employers you might have might not permit certain types of connections.

You will also need to be able to use the Internet as well as the telephone line at the same time. This is typically not an issue if you have a broadband connection which is already a requirement anyway. There will likely be various requirements for the type of telephony hardware that you need for the job, depending on your employer.

All of the above are probably things you have already. Since so many people these days have at least one computer in their household and broadband Internet access, these are unlikely to become extra expenditures. However, you may well find it preferable to have a dedicated computer which only you have access to. Using the primary family computer as your primary work station is generally not a good idea for security and reliability reasons.

You will also need to spend a bit of money on a decent headset. Something that has a high quality noise cancelling microphone is a must. However, these are not too hard to find and do not cost a great deal of money. In fact, there is unlikely to be any reason why you would need to spend more than about $25 on this.

Your working environment should also be taken into account. Your employer will most likely require that you have a separate room to work in and no interruptions such as noisy air conditioning units etc. Simply put, there must be minimal background noises in your work place.
