Previously all our communications ran over copper networks and the internet did not exist. As a result voice travelled in waves. Nowadays due to vastly improved network and the development of the Internet Protocols (IP) voice travels the same way as data on our IT networks using binary code. This has resulted in the capability to use Voice over internet protocol (VoiP).
There are 3 types of solutions that use VoiP:
- Part IP enabled telephony systems
- Whole system IP working
- Hosted VoiP
Part IP enabled telephony systems/Whole system IP working
A system normally sits in your workplace and works off BT landlines or a good quality internet or fibre connection. Phone systems provide a better level of resilience as they are dependent on the quality of the internet connection.
