The National Portrait Gallery had an ageing analogue switchboard,
which was starting to suffer failures and leading to concerns that
the hardwiring was not effective long-term – especially since the
original manufacturer could no longer supply spare parts.
The Gallery’s requirement was for a modern IP system, with capacity
for up to 250 extensions, installed on their data network. The
system would need to be capable of handling new communication
protocols such as VoIP, as well as providing standard telephony
features such as direct dial, call forwarding and voicemail.
