The first step is deciding when/if it might be beneficial to move from a traditional voice network to a converged network. Each company is different, but two key indicators are intra-site call charges and the need for a more agile telephony system geographically (eg. distributed call centres). For many companies the cost of converting is too high to balance the cost savings. Simply changing your voice supplier might be easier and generate better cost savings.At the moment the whip hand is with PABX manufacturers moving into the IP market, rather than the IP hardware vendors moving into voice - but the hardware market is far from dominated by any single player. IP-enabling an existing PABX infrastructure is often the way forward in conjunction with planning your WAN carefully. This would suggest going for a PABX specialist for this element. If Cisco (et al) is your bag, then look for IPT accreditation and keep an eye on references and proof.Be cautious about accepting too pat technical information from sales people. QoS is not strictly necessary to carry voice and can carry quite a cost premium. Neither are uncontended DSL services strictly necessary. We have people running 3-4 voice channels concurrently between sites on strandard contended ADSL (20:1) with simple packet prioritisation at the edge to protect the voice from e-mails and printing traffic.There's no single solution. Find a solution provider that you can work with, with track record. Carefully consider the costs of change against the cost benefits as they are often not clear. Ensure you consider UPS protection for IP equipment essential for voice delivery - or have a back up analogue telephone option.Before simply installing VOIP... take a step back and look at the larger communications picture in your single or multiple location company. You will see a number of Horizontal Communications paths:ACCESS / BANDWIDTHMAIL & GROUPWARE/FTPIMS to provide- CHAT (IM/Online Presence)- Voice+ (SDP/SIP/etc.)Presence... the users "online reachability"... is the empirical parameter.Companies often DIY their email/IM/Voice systems & protection schema's, but these exist as industry standard solutions today... Why not outsource that effort to an Industry leading Service Solution provider & then just focus on the business?Your biggest challenge is actually to find a Hosted Service Provider who is already on the Convergence Path (there are VERY few)... A Service provider who offers "Presence" (user log on/reachability status) similar to the MSN/ICQ/AIM/YIM/Skype. A service provider who offers this, can1) bill you appropriately for "online reachability" rather than the call-by-call (or monthly subscription) basis...2) offer not just secured VOIP, but also IM/Mail/Video/Collaboration/etc. via SIP on an IMS infrastructure.If you have day to day responsibility for the opertion of a multi-location VoIP network - there are some issues to be aware of.1) It's not as cheap as vendors want you to believe2) Legacy equipment manufacturers do not have the best products and may not be the best solution. Remember the old adage about IBM from the 60's.... "no one was ever fired for buying IBM". Now it seems to be buying Cisco or Nortel kit is the "safe" option.3) There is a support cost that older management types will not get or possibly understand. That the LAN just became extremely important in the overall comunication infrastructure. It isn't just for e-mail anymore.No matter your final decision....keep in mind that everyday is an adventure. Be careful - be wary and test, test and test again.
Rows and rows of software on sale are available in any computer store today. Although they are tempting, buying software off the shelves holds a few problems of its own. Commercial software can be incompatible, outdated as well as expensive compared with what is available online. Although it is not new and it is one of the most overlooked opportunities in the computer industry, there is another option to commercial software. This alternative is the use of shareware, software you can try before you buy.Shareware has been around for years and its competition with commercial software is intense. Still it seems to be untouched by many new computer users, advantages over commercial software notwithstanding. Shareware represents a very interesting concept indeed.Shareware is more economical compared to most commercial software. However, keep in mind that economical does not mean low quality, there are many examples that prove shareware will often outperform the quality of commercial software. Shareware offers the opportunity to try before you buy; thereby giving you the opportunity to find out if the software is indeed compatible with your computer system before making a purchase. Keep in mind that the commercial software policy leaves no allowance for its return and you cannot take them on loan to find out if you can use them and actually like using them.Another advantage of shareware over commercial software is that it is legitimate while offering you the ability to test the latest version of a shareware program.Shareware is available all over the Internet. Shareware is bountiful in download libraries and many companies and independent programmers offer shareware from their own websites. Simply entering keywords related to your program of interest into a search engine will see you receive many results of Shareware available to you.You should also keep in mind that you may not experience a full program as you would if you bought the software out of a box. Shareware may or may not be limited, which means that some of its functionality may not be available to you until you have paid for the program. These limitations are normally small and do not interfere with the core operation. Actually, they are devised in such a way as to encourage purchasing of the software. Shareware is not freeware and you should not expect it to work indefinately. At some stage you will have to pay to enjoy the functionality that the sofware offers.The only similarity between shareware and commercial software is that they can both be paid for with a credit card. With a credit card, you can soon be the owner of a Shareware program that exactly fulfill your needs.
Ensuring the Safety and Security of Your Home ComputerWith the popularity of and the reliance on the Internet by almost the entire world population, there are suddenly a lot of things you can do and know with literally one click of the mouse. Making purchases nowadays doesnt require you to go to the shop or store; you can buy items online. Researching for various pieces of information can now be accomplished via the Internet.However, there is an unfortunate reality that goes along with the wonders of the Internet. It also thanks to the Internet that computer security is always an issue. With the continued growth of the dependency of people (including businessmen, offices, government officials, and more) on computers and the Internet, this is a more important issue than what most believe.If you are a home computer user, you still need to make sure that your computer is safe from any form of malicious online attack, including hacking. You might have important data (including any identification) in your computer which intruders can have access to. That being said, it is important for you to find out just how safe your computer is from these potential attacks.The very first step before actually tinkering with your computer is finding out the motive of intruders and why they target home computer users. They do this because (1) home computer users typically dont have security measures installed to counter them, which makes them easy targets; and (2) they often have valuable information stored that is enough to entice these intruders, such as credit card information. Think about it you might potentially be a target. The registry keeps growing when you use Windows. As it does, it attracts obsolete information and becomes cluttered. Get Free Registry Cleaner Scan here!Following that, you have to know what types of attack to expect it is usually via email or clicking an ad-banner on a website. Opening an unknown, seemingly innocent email or clicking on an ad-banner will sometimes put you at unwanted risk and open the door for intruders. Once theyre in, theyre sometimes hard to get rid of, so your home computer security should start with you being careful about the things you do while connected to the Internet.
Are you a small retail business owner looking for a way to speed up the waiting time of your customers when they are at the cashiers? Then POS barcode scanners can help you with that.POS barcode scanners or point of sale scanners will allow the cashier to scan the product and all the important information such as product category, product code, pricing etc will be digitally recorded. This process is very fast and easy to learn. The only difficult part comes when you need to tag all your stores items with a barcode in order for the POS barcode scanner to be able to read.Another advantage of using POS barcode scanners is that all recorded information is easily retrievable. This makes it easy to generate accounting data, ledgers etc convenient. Also the inventory levels in your store can be easily identified as well.POS barcode scanners are not just useful in retail outlets but also can be used in clinics, libraries and any other business or organization where a large quantity of items are being transferred/purchased each day.There are 2 types of POS barcode scanners. They are CCD-based and laser-based.CCD-based POS barcode scanners are more common and cheaper, however they have a disadvantage in that they cant read rounded surfaces. So if you have products which have a smooth curved surface, it is better to use laser-based barcode scanners.Laser-based barcode scanners can read from any surface and can do this at a greater distance than CCD-based barcode scanners. This is because CCD-based scanners uses cameras to capture the barcode information hence they need to be within close distance of the barcode in order to capture the barcoding information.An important type of barcode scanner is one that uses CCD technology. This technology was widely used in many retail outlets and involves scanning by pressing the scanner on the barcode to feed information into the computer. But its inability to read from round surfaces has resulted in the development of laser-operated scanners, which pick up barcodes from the surface of products even from a distance. With the advent of omni-directional laser scanners, more and more dealers are opting for those barcode readers that send out laser beams in different directions and pick up the barcodes on the products in a matter of seconds.There are a wide variety of POS barcode scanners available in many different configuration depending on your market sector. Some uses USB, others wireless and some are handheld.I personally prefer handheld POS barcode scanners from Symbol and Datalogic. I found they have the best support and handheld POS barcode scanners are light and portable and can easily to transport to other location as I see fit. You can check out their websites for their range of POS barcode scanners.
College students spend an enormous amount of money on day to day living and school expenses. Dorms, books, and food alone will cost parents thousands of dollars per semester. Finding places to cut costs can be difficult, but one major expense can be avoided. Laptop computers are very quickly becoming a necessity for any student, and they are costly. Finding a cheap laptop that will get the job done can save a great deal of money.Many have found the answer in Refurbished Laptops. A refurbished laptop is one that has been returned to the manufacturer and has been restored to a like new state. Although the computer is not damaged, it cant be sold as new so the price is slashed heavily. A $2000.00 laptop might be sold as a refurbished item for $900.00 and be no different that its new counterparts. This means that for less than half the cost, a powerful like new laptop can be purchased, and in many cases be placed under warranty in the same way a new laptops would. Almost every major computer manufacturer offers refurbished laptops including IBM, Hewlett-Packard, and Dell.Once a refurbished manufacturer is chosen, the laptop specifics must be looked at to make sure the computer can get the job done. Students are looking for a laptop that is:Sturdy Students are on the move, and their laptop will take some damage in its time. Make sure the computer is tough.Fast The computer needs to keep up with the student so processor speed and memory is very important. These are not the two areas to cut cost.Light Weight No one wants to carry a 50 pound boat anchor around in their already heavy book bag. Make sure the refurbished laptop is as portable as it needs to be.Wireless The laptop should already be wirelessly enabled or have an open slot for a wireless card. Universities are becoming wireless hot spots and every student should be able to take advantage of this.Powered Make sure that the life of the laptop battery is respectable, and purchase a rechargeable back-up so there is always battery power available.There is more that should be considered of course, but most options will depend on the needs of the individual. One drawback of a refurbished laptop is that in most cases there is very little customization that can be done before the point of purchase. These computers are already built and ready to go so if you dont like a particular option then you need to buy another laptop. This doesnt mean that changes cant be made by the user after purchase, but any further customization will cost additional money and the user needs to be proficient in making the upgrade.
