VoIP has changed the face of communication, saving both personal and corporate users thousands of pounds each year. Whereas international phone calls were previously cost-prohibitive, VoIP has opened the doors to the world. With innovative and cost effective VoIP phones now available, such as the Siemens Gigaset S685 IP Dect Phone [1], utilizing VoIP technology has never been easier.

To help you get on board, let us take a look at the frequently asked VoIP questions.

Q: What are the advantages of a VoIP System[2]? A: VoIP offers many advantages, including the following:

• Easy to use • Cheaper than a conventional phone system • All VoIP to VoIP phone calls are free • You can have various incoming phone numbers in different area codes • Unlimited call capacity • The ability to view the detailed statistics of your calls

Q: Do I need a broadband connection to make calls? A: Not exactly, but it is highly recommended. VoIP calls made over dial-up and ISDN modems tend to have poor sound quality. A DSL line with an upstream of 256k can support up to 4 concurrent calls without flaw.

Q: How is the call quality? A: The call quality with a broadband connection is excellent. Before installing a VoIP phone, you should inquire within your ISP and find out how much bandwidth is available. This will ultimately determine the call quality.

Q: What about the hardware? Is it reliable? A: There are various factors to be weighed when it comes to reliability, though it mainly boils down to the service provider’s equipment. Keep in mind that a VoIP server is merely a computer, and like all computers, they are prone to endure problems at the most unlikely times. A service provider’s reliability lies in its infrastructure which should consist of redundant monitoring and backup systems. This way, if anything should go wrong, the problems can be instantly resolved to ensure minimum downtime.

Q: Can I use phone numbers I already have? A: If you live in the greater London area, existing numbers can generally be used for VoIP. If not, you can apply for a number in your area and then redirect it to your existing number.

Q: What type of phone number will I get? A: This all depends. You have the option of obtaining a geographically located phone number with an area code that begins with 01 or 02. If you want to select your own number that is easier to remember, a minimal fee may be required. Otherwise, you will be given a number based on your location.

Q: How many numbers do I need? A: This depends on the number of phone calls you expect to have at one time. One number generally gives you up to 2 calls: one inbound and one outbound. You can also have to up 10 internal extensions.

Q: Can I redirect VoIP calls to my Voicemail or another phone number? A: Yes. This may require an additional fee which is typically the standard charge for an outgoing call.

Q: What happens if my internet connection fails? A: VoIP thrives off of the internet. If the connection fails, your phone will not work for VoIP calls.

Q: Can VoIP phones call any number? A: VoIP phones can call most ordinary phone numbers but generally no emergency services. For instance, no calls can be made to 999. In the event of an emergency, you would have to place the phone call over a mobile phone or cordless phones.
