Mitel 3300 Dial Tone Users normally hear continuous dial tone when they lift the handset.

They hear discriminating (also called interrupted), or transfer dial tone under certain conditions.

Dial Tone -Outgoing Calls - The system can provide a pseudo-CO dial tone to prevent possible confusion to station users.

January 2012: Telefonix Voice & Date and Mitel have parted company, and we no longer carry the Mitel telephone system, deepening our specialisation in Avaya IP500 instead. This leaves us, however, in an excellent position to compare the Mitel 3300 phone system and the Avaya IP Office phone system: please contact us using the web or on 01252 333888 if you wish to discuss these phone systems.
