Business Telephone Systems

Whether you use a traditional PBX system over ISDN lines or the latest cloud-based hosted IP telephony solution, the handsets and functionality of a telephone system contribute to the operating efficiency of the organisation. STL offers a complete range of on-site telephone systems from small offices to large multi site enterprises.

Although traditional PBX telephone systems remain popular, many more businesses are now switching from traditional ISDN telephone lines to SIP trunks or hosted PBX services, routing all their voice calls over their data connection. Why? Because SIP and hosted can provide cost savings of up to 70% over ISDN as well as a host of other benefits that can make a business work more efficiently.

Find out how leasing your telephone system could help you take the next step with your system.

ISDN Switch Off

BT have stated they will be shutting off all ISDN lines from 2020 with the project to finish in 2025. This means businesses with ISDN lines will now be put under further pressure to move to either SIP or cloud hosted telephony. Learn more about the ISDN switch off.
