Telephone Systems

There are 3 main categories when it comes to telephone systems these days and they are:

  • Analogue and Digital (Extension and Trunks with a Server on site)
  • IP and SIP (Extension and Trunks with a Server on site)
  • IP and SIP (Extension and Trunks with NO Server on site)

IP = Internet Protocol
SIP = Session Initiation Protocol

You can also mix and match the above to give your company that bespoke solution which will give you resilience, flexibility and cost savings. Most small traditional telephone systems are based on Analogue and Digital extensions with either Analogue (PSTN) Trunks or Digital (ISDN) Trunks.

New start-up or small businesses are now looking at server-less solutions (cloud based), where no on-site server is required. This can be deployed quickly and cost efficiently. Companies which have admin staff and the budget to look at an on-site solution which benefit from:

  • Less outgoing rental costs
  • Only paying for rental of the trunk services
  • Not having rental cost per extension
  • Extension costs are included in the on-site solution

A mixed telephone solution (on-site and server-less) together can be a good mix for your main office which may have digital or IP telephones, depending on the type of cabling within your office location.

Having a mixture of digital trunks (ISDN) and SIP Trunks (IP) with SIP phones for your remote workers will enable your office workers to transfer internal calls or external calls to them.

This is easy to setup at a very low cost and the calls would be free between the remote worker and office as it is classed as an internal call.
