Conferencing can mean many things:

To "conference" (chat, voice, video) with WOL staff, the Microsoft Teams app can be used.

To do a multi-party conference call, that can be done with the conference feature on your phone.

To host a web meeting or conference, we have an app called Zoom, which some departments have and use regularly.  Ask the ITS department for assistance.

For the Mitel Connect app: We do not posses the equipment for this feature at this time, nor are we planning to use this system's conferencing feature.
