You bought the wrong phone Lindsay. This is a system phone and only talks to the System Control Network Box. It won't work as a standalone phone. The system box is the equivalent of a company switchboard operator.

No. The Mitel Superset 4015 is a proprietary digital phone that will only work on Mitel telephone systems. It will not work on some of the older analog Mitel systems.

Here is the manual it is all explained in it. Link below. edocs.mitel.com/UG/EN/2ICP_4025_UG_R2_EN.pdf

Sorry to tell you, but the Superset 4015 is not capable of doing this conference feature.

It has loud speaker capabililties (for paging, or listening to calls), but no microphone for your conference meeting.

The time and date come from the Mitel Telephone system, not from the telephone set itself.

You need to access the Mitel system to make a time change.

If you can get into the system, goto the Group Administration and click on time...the rest is self explainitory.
