The Centrex Internet telephony service; some notes to business users.

VOIP – Voice Over IP = Internet telephony.

 

The principal benefit offered by the Centrex VOIP service to your business is not simply to save you money with free or cheap phone calls and a reduction in the number of BT lines you need, but to allow you to present your business in a professional way to your customers. You may be hard pressed, working partly from the office, partly from home and on the road, but your customers will have a consistent, straightforward way to reach you – simply by ringing your main business number. VOIP Centrex features are normally only available on top end phone systems that are expensive to buy and maintain, and big companies pay ten to twenty pounds per extension per year for them.

 

To install it you need broadband and a VOIP supplier (that's us hopefully). You need at least one VOIP telephone number and some VOIP phones. These act like extensions on a traditional office phone system.

Why you should consider Internet telephony for your business.

 

VOIP telephone numbers are now available for all UK area codes, so you can have a number with the area code of your business location. This is what your customers expect.

 

·         Incoming calls.

Customers calling your number hear a normal ringing tone and pay their normal UK landline rate.

·         Always be available.

Incoming calls can be transferred to any extension, but VOIP Centrex offers the huge advantage that an extension does not have to be physically within your office, it can be located anywhere that broadband is available. This is very good news if you have people working from home or you operate split sites. Neither the caller nor you pay any onward call charges - the call is transferred free over the Internet – even if the extension is in another country! A real bonus if you have staff working on site or directors who sometimes work from a second home.

 

‘Follow me’ - if a call is not answered within your set time it can be forwarded - to your home, your mobile and so on. You can choose to forward certain extensions, service engineers perhaps, straight to their mobiles without waiting. (Calls forwarded to VOIP phones are free. Calls forwarded to landlines or mobiles are charged to you as an outgoing call.)

 

·         Outgoing calls.

VOIP phones are just like normal phones - you lift the handset, hear a normal dial tone, dial and hear a normal ringing tone - and they are available in a range of styles and costs. There are also small adaptors which convert standard analogue phones to  VOIP phones. Outgoing calls to other VOIP numbers, including your extensions, are free because they travel over the internet, but if the call is routed onto the normal phone or mobile systems you pay, but at very competitive rates.

·         Voice quality.

VOIP calls do sound a bit different to normal landlines, but that is because they are better quality! Modern VOIP systems are reliable enough and of good enough quality for business use. You may wish to keep a fall back system or phone on a landline in case broadband fails, but our experience is that broadband is as reliable as electricity, and if either one fails you are dead in the water anyway.

 

What does it cost.

 

A VOIP telephone number, allowing two simultaneous calls, costs £7 per month for the full Centrex service. As each VOIP number acts as a two line hunt group* you really have the equivalent of two lines for £21 per quarter - a big saving on the BT standing charge. Simply decide how many calls you need to be active at once and half it to see how many VOIP ‘lines’ you need.

* A two line hunt group is two phone lines that respond to the same telephone number, so if one line is busy you can still use the second line to make an outgoing call or to receive another call. 

Extensions do not attract a monthly cost, just the capital cost of the VOIP phones and/or adaptors. Adaptors, which convert normal phones into a VOIP phones, cost typically £40-£50 each and phones cost £60-£150. If you really need to keep costs down you can use a ‘soft phone’ (a computer program), which is available free.

 

Our VOIP call rates are excellent – 1.2p per minute to UK landlines during office hours and 12p per minute to mobiles. International rates of 1.5p per minute to 35 overseas destinations are hard to argue with either. Of course VOIP to VOIP calls are always free, which means that all calls between extensions are free – even if the extensions are geographically separate - and calls to other VOIP telephone numbers are free. With more and more businesses moving to VOIP its easy to see how your call costs will keep falling.

 

Try it.

 

There is no longer any reason to put off using internet telephony for your business – you can reduce the number of telephone lines you rent, pay lower call charges and present a totally professional image to the outside world. There is a lot more that can be said but why not sign up for a free 3 month trial and see for yourself - £10 of call credit is the extent of your risk!

 

 

FAQ - frequently asked questions.

 

- Why should I pay for a service I can get free with Skype?

- We use Skype, but not as a business tool. None of the free services provide all the important features a business needs - standard phone numbers, easy transfers between extensions and  'follow me', for starters.

 

- Can I transfer my existing number to VOIP?

- Not usually. You may wish to hedge your bets initially and keep your well known business number on the normal phone system and migrate slowly to VOIP. Or go for it, cancel the lines and number, chuck out the old PABX and ask BT to provide a recorded  message saying 'the number you are calling has changed...'. It all depends on how brave you feel.

 

- What about my fax, lots of customers send in orders by fax?

- Same answer as above really. There is nothing to stop you putting a fax on a VOIP number but faxes can't hear recorded messages saying the number has changed. So we kept our fax number and BT line, provisioned that line with broadband and connected both the fax and router to it - its easy, just plug them both into the splitter - and got rid of most of the other BT lines.

 

- Will VOIP phones work if the power fails?

- No. But neither will your broadband or computers.

 

- What if broadband fails?

- VOIP needs an internet connection, but so do many of the activities of a modern office, email, web site maintenance and so on. For prudence sake its probably worth keeping a phone and fax on a normal line.
