Mitel 3300 XNET is Proprietary switched MSDN/DPNSS networking over the PSTN.

Also supported is a Hybrid XNET configuration. Hybrid signalling delivers voice over PRI channels, with MSDN call setup, feature invocation, and tear-down signalling over the IP network. Full XNET DPNSS feature transparency is maintained.

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.
