BT SIP trunk: Harlow College case study

Harlow College’s ageing voice service was expensive with limited functionality – it was impossible to hold an internal conference call and there wasn’t even the option to make hands-free calls. It was time for a change. So they looked to BT to offer a solution.

Collaboration was really tricky with Harlow College’s phone system. So they called their BT Local Business team to see if they could help.

“BT found they could provide a new communications platform, while halving our ongoing costs,” says Dave Higgs, Senior Infrastructure Engineer at Harlow College. “With a return on investment inside three years.”

The fully-inclusive package included lines that connected lifts, alarms and emergency phones; BT Business Broadband served CCTV and onsite catering operations and BTnet Leased Lines gave the college reliable and fast internet access. All for a set monthly fee.

To minimise disruption, we moved existing direct-dial numbers over to the BT SIP Trunk service, allowing the staff to keep their existing numbers. Plus, when vast numbers of calls come in from prospective students in August, the school is able to temporarily increase the number of SIP trunks to cope with the additional call volume.

Incoming calls are now answered by an auto attendant, which steers the caller to the correct department. Plus, there are now voicemail facilities and multi-party conference calls can be set up instantly – making collaboration easy.

The new solution has brought our communications facilities right up-to-date. SIP trunking is an innovation. Voice quality is perfect and it’s much more cost effective. Our ongoing costs have halved, exactly as BT said they would.
