Telephony Support Service (VoIP)

About the Service

The Telephony Support Service (VoIP) offers support for Voice over IP (VoIP) systems installed by BT Lancashire Services. Our VoIP systems are designed to provide internal phone extensions and to link to your external phone lines and your current telephone number.

VoIP telephony allows your school to make telephone calls between the internal phone extensions and externally, using your existing IT network data cabling to deliver the telephony internally around your school. This reduces the need for separate internal telephone cables and associated expense, making it easier to expand the school's internal telephone system. The service uses a server to act as a PBX (Private Branch Exchange or internal telephone exchange), which also reduces the costs associated with buying and operating a physical PBX.

What are the benefits?

VoIP technology enables the school to have any number of internal telephone extensions and potentially reduces the number of external lines, reducing costs and improving internal communication. The VoIP phones plug into network data points (the same type of socket PCs plug into).

Future expansion is more cost effective than with a dedicated telephone system using its own cabling. Using PoE+ (Power over Ethernet) switches also removes the need for power cables and adapters for the telephone handsets, freeing power sockets for use by other devices or the need to have additional electrical sockets installed.
