Telephony services offered by Heathrow include both analogue and IP telephony based on Cisco’s call manager technology. The different technologies both facilitate cost effective access to the public switched telephone network (PSTN) with national and international access for both inbound and outbound calls.
The digital telephone lines are based on making use of the existing pan-campus LAN network. Via the network, phones can be managed, configured, and supported by Heathrow staff. The extension numbers and calling restrictions can be set up remotely without any end user involvement. Any saved voicemails are clearly indicated and easily accessible.
Analogue lines are still a preferred connectivity option for certain devices. It can be used to terminate a standard analogue phone, modems, fax machines and PDQ machines. Secure ATM connections or alarm lines also make use of analogue lines. Heathrow makes use of VG gateways on its campus wide network to deliver analogue lines.
