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

	Session 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.		Call 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.

	Scheduled One-Off Meetings Planned Feature		Scheduled Recurring Meetings Planned Feature

	Duration: Absolute period of time spent in a call or session. So if three users are in a call, the duration is the length time from the first person joining to the last person leaving regardless of the number of users.		Time Spend: The total cumulative time spent by users on the call. If three people are in a concurrent call each of their time is added up.
	Attendees Any user agent in a call. This includes participants but also bots, together mode, and other other non human elements within the call.		Participants A human that is communicating in a call.

	Internal Attendees that were from within your tenant.		External Attendees that were not from your tenant.
