tyGraph Calling General Terms

Terms matter a great deal. People often use terms like Meetings or Calls loosely but at tyGraph these mean specific things.

General Terms


The basic building blocks of calls. A session a continuous communication between devices in Teams. If a person joins a call, leaves, then re-joins the same call that is two sessions. If a person joins on two devices those are also two sessions. If a person joins a call and turns on recording that is two sessions.


A generic term for a communication between two or more devices. This always involves two or more sessions. This can be further categorized into: Direct Calls and Group Calls

Direct Call

A call between one other person. Sometimes people refer to these as Peer to Peer calls.

Group Call

A call between more than one person.
