about us

Whatever the size of your business, Pinnacle can install any telephone system you want, enabling you to achieve your business objectives efficiently and economically.

Internet Protocol (IP) is the future of telecommunication. BT will be implementing its 21st Century network in London shortly and the backbone is IP.

Pinnacle installs SIP (Session Initiated Protocol) lines which send phone calls via the internet, with a high level of quality. You can reduce your call costs by at least 30% and retain excellent quality.

To maximize resilience and savings Pinnacle strongly recommends a combination of IP and BT lines. You need a system which continues to function in the event of any problems with your IT network. Pinnacle is a fully accredited Avaya Silver Partner and often recommends an IP enabled phone system rather than a ‘full’ IP system.

One call – your telecoms answered! Pinnacle is proud if the one point of contact service it offers you, from installation of your new system to the ongoing annual maintenance. Pinnacle has strong relationships with the largest telecoms companies, including BT and Maintel.

Pinnacle also has vast experience of customers who have an office in London with other sites throughout the world. You will be looked after wherever you have your offices.
