Expert Review Review by Best4Systems

System Phone suitable for: SMEs & Large Enterprises

Major benefits:

  • Fully duplex handsfree speakerphone
  • 12 programmable softkeys – to personalise your phone
  • 8 Function keys, include transfer, call forward, hold, cancel and do not disturb
  • 2 line 20 character back lit screen – white background highlights the graphics
  • Speed dials

Overall assessment:

Mitel have always produced high quality IP phone products to go with their Mitel Unified Communicator Express, Mitel Collab Client, Mitel 3300, and other unified communications solutions.

The current portfolio includes the Mitel 5312 – the workhorse of the range aimed at technical assistant, everyday users, and managers. The 5312 can also be equally used by ACD agents when incorporated into the Mitel MiContact Center, and Mitel MiContact Center Office environments.

As ‘standard’ phones fair, the Mitel 5312 has more functionality than most of its rival brands and is priced very keenly. Overall a good value proposition that most It managers would have no hesitation but to roll out the Mitel 5312 to their users.

Great overall functionality and value Review by James L

This is one of the entry level phones in the Mitel range, but is much more highly featured than you would expect. Great layout, 12 programmable keys and a really good quality speakerphone. We have also bought the refurbished units which are amazing value.
