Very simply, VoIP is sending telephone calls over the Internet. VoIP stands for
“Voice over IP”, where IP means Internet Protocol.
What can VoIP do for me?
VoIP can dramatically reduce you telephone costs, whether you are an end user or
a company looking to save on PBX costs.
VoIP for Business
The benefits of VoIP don't stop just with reducing call reception costs to
roaming users. Utilising our SIP Trunking service, a company can replace all of
its traditional telephone lines, from single user PSTN lines all the way to
ISDN30 trunks, with a VoIP connection. For a company with multiple locations the
savings can be enormous, as all internal calls, even international ones, between
VoIP users are charged at just 1.75p per miunute. Remote workers can log into the VoIP
service from anywhere, and hence both their internal, and any DDI number
allocated, will “follow” them wherever they connect from. When out in the field,
a worker's Smartphone can double as their desk phone, resulting in significant
time savings when colleagues need to get in touch and would traditionally have
to try several numbers, or leave voicemails which then have to be collected,
listened to, and responded to.
VoIP enabled PBXs are replacing older systems in many businesses, the Switch
VoIP system is fully compatible with the industry standard SIP and IAX
protocols. SIP is most commonly used for VoIP telephones, IAX is used for
connecting VoIP PBXs together, and can also help where firewalls make SIP usage
impractical, our system is configured to make both protocols available to all
users by default, ensuring maximum compatibility.
VoIP for Individuals
Many business people nowadays have number forwarding, where their business
number, whether it's an 0845, 0800, or traditional 01 or 02 number, is forwarded
to a different location, so they can receive business calls on their mobile
phones, or at various offices, whenever and wherever is convenient, instead of
being tied to their main desk phone to stay in contact. Forwarding calls can be
expensive however, as the number provider has to charge the person receiving the
call the cost of sending it over an external network, and in the case of mobile
networks the charges can soon add up.
However, if the person receiving the calls uses VoIP to connect to their
telephone service, then there are no high mobile network charges involved, and
the forwarding service can be provided at a much lower per minute price.
How does it work?
The end user purchases the VoIP upgrade from Switch. We then provide a username
and password, with which the user can then log in, from anywhere in the world,
over the Internet, to receive their calls. When someone dials the user's number,
we route the call to our VoIP server cluster, which in turn contacts the VoIP
application the user has logged in from. This could be an app running on the
user's smartphone, a “softphone” running on their computer, or a dedicated VoIP
telephone plugged into the local LAN or connected by Wi-Fi. Our advanced
telephone infrastructure handles all the conversions needed between the caller
using a traditional phone line and the recipient using VoIP.
What's the call quality like?
Call quality does depend on having a reasonable Internet connection available,
but as long as the end user has access to a connection with reasonable bandwidth
(which can include Wi-Fi networks as long as they are not overloaded), call
quality is easily as good as on a traditional telephone, and can in some cases
be better. On any good quality broadband connection, call quality will be
indistinguishable from a landline phone call.
What happens if I want to receive calls where there isn't a sufficiently good
Internet connection available?
With Switch, you have the choice of up to three different “targets” for your
forwarded number to go to. If any of them are unavailable, the system
automatically routes the call to the next one. So you could set your VoIP
service as the first target, with a fallback to your mobile number, and failing
that, your office's reception number. If you are without an Internet connection
but have mobile coverage, the call will be forwarded to your mobile number, but
any time you do have Internet access, you can avoid the cost of mobile call
charges by using the VoIP to receive your calls. If you're somewhere that has
neither Internet nor mobile coverage, your receptionist can receive the call so
the enquiry isn't lost, or you could use our voicemail services to receive such
calls.
