How to Make Conference Calls in TSN Phone

Applies to: Windows 10/11, macOS, iPhone, iPad, Android, and Supported Web Browsers
Difficulty: Beginner
Estimated Time: 5–10 minutes

Overview

TSN Phone allows you to communicate with multiple people during the same telephone call using conference calling features. Conference calling can be useful when you need to connect a customer with several employees, coordinate with different departments, or discuss a project with multiple participants. Depending on your organization’s configuration, you may be able to start a conference directly from the TSN Phone application or join a scheduled conference using a designated telephone number or conference extension. This guide explains how to start a conference call, add participants, manage an active conference, and troubleshoot common conference calling issues.

Before You Begin:

  • Make sure you are signed into your TSN Phone account.
  • Confirm that your extension is active and connected.
  • Verify that your internet connection is stable.
  • Have the telephone numbers or extensions of the participants available.
  • Use a working microphone, speakers, or headset.
  • Confirm that conference calling is available for your extension.

Important: Conference calling features, participant limits, and available controls depend on your organization’s phone system configuration.

Note: A conference call is different from a call transfer. A transfer connects a caller to another destination, while a conference allows multiple participants to remain connected together.

Understanding Conference Calling

TSN Phone may support different conference calling methods.

Three-Way Calling

Three-way calling allows you to connect yourself and two other people into the same conversation.

Example: You are speaking with a customer and need to include a coworker. Instead of transferring the customer, you add the coworker so all three people can speak together.

Multi-Party Conference

A multi-party conference allows several people to participate in one call.

Depending on the configuration, participants may join from:

  • Internal TSN Phone extensions.
  • External telephone numbers.
  • Compatible desk phones.
  • Supported desktop or mobile applications.

Note: Maximum participant counts depend on the conferencing service and your organization’s configuration.

Conference Room

Some organizations use dedicated conference extensions or conference rooms. Participants may call a designated number or extension and enter an access PIN when required.

Important: Conference rooms and access credentials are provisioned by True Synergy Networks. Users should only join or use conference rooms assigned to them.
