Public Switched Telephone Network is also known by many Brtians as landline telephone service. Thwe current landline system was created over hundred years by a Canadian named Alexander Graham Bell, which is his name is present on Canada's telecommunications company which is called Bell. Bell is the equivalent of Britain's BT which is also known as British Telecom. Bells new telephone system eventually took the place of the telegragh system, which was phased out over time, and the last telegraph service was used in 1959.

mail, e-mail, and web or phone conferences. Few telecom companies can 
delivered these services by all means of communications, including 
mobile telephones. VoIP also allows both voice and data communications 
to be run over a single network, which can significantly reduce 
infrastructure costs.The prices of extensions on VoIP are lower than for Private Branch 
Exchange or PBX. VoIP switches may run on commodity hardware, such as 
personal computers.

 to give your business more efficient service in some areas as well. 
However, your first port of call could be to decide whether you want
