IP
telephony:
Unlike phone systems of old, which use thin two wired cables, modern day phone
systems like the foncordiax use standard network cabling (cat5) used in virtually
every office to connect computers together. IP handsets simply convert conversations
into digital media which is then passed along the network cable to the phone
system.
Foncordiax control units simply plug into existing network routers and phone
lines.
Foncordiax handsets plug into existing computer network (simply unplug network
cable from back of PC, plug this cable into handset. Then take the supplied
network cable and plug this into the handset socket marked PC and the other
end back into the PC):

Advantages:
But
I use traditional phone lines…
Traditional phone lines (Analogue/ISDN/RDSI/T1/E1) are connected to the foncordiax
control unit with standard phone connectors. Conversations are held in exactly
the same way as normal in superb quality.
Then why use IP
Digital (IP) telephony allows a convergence of voice and data offering a huge
array of additional features like caller recognition, voicemail to email,
directory services, video conferencing, faxing, music on hold and database
integration to name a few, features which can make a company significantly
more efficient.
Voice over IP (VoIP)
All foncordiax systems are VoIP enabled which means they can carry phone calls
literally over the internet. Digital calls by their nature are of a far higher
quality than traditional analogue calls, and when calls are made between foncordiax
systems are totally free of charge, with calls to landline or mobile phones
often far lower than normal.
Summary
The common consensus is that IP Telephony Providers have recently reached
a quality level where basic service matches that offered by traditional Telcos
and Centrex systems and that the advantages offered in terms of featureset
and price now make IP systems the obvious choice for the future.
