How to Change Your Ringtone, Audio Devices, and Notifications 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 customize how your business calling application uses your microphone, speakers, headset, and notification sounds. Correct audio settings are important for hearing incoming calls, speaking clearly with customers, and receiving alerts when coworkers send messages. Depending on your application version, you may also be able to change your incoming call ringtone or select a separate device for ringing. This guide explains how to configure audio devices, change available ringtones, manage notifications, and troubleshoot common sound-related issues.

Before You Begin:

  • Make sure you are signed into your TSN Phone application.
  • Confirm that your device is connected to the internet.
  • Connect your headset or other audio devices before configuring them.
  • Make sure your device’s volume is turned up.
  • Verify that the application has microphone and notification permissions.
  • Confirm that you are using the TSN Phone application approved by True Synergy Networks.

Important: Available ringtone and notification settings vary by application version. Some versions use administrator-managed or built-in sounds that cannot be changed through the normal user interface.

Note: TSN Phone may provide separate audio settings for your microphone, speakers, and ringing device.

Understanding TSN Phone Audio Devices

The TSN Phone desktop application may allow you to select three different audio devices.

Microphone

The microphone captures your voice so callers can hear you.

Examples include:

  • A headset microphone.
  • A laptop’s built-in microphone.
  • A USB microphone.
  • A compatible Bluetooth headset.

Speaker

The speaker plays the audio you hear during an active telephone call.

Examples include:

  • A headset.
  • Laptop speakers.
  • External computer speakers.
  • A compatible Bluetooth device.

Ringing Device

The ringing device plays the sound that alerts you to an incoming telephone call.

For example, you may want:

  • Call audio through your headset.
  • Incoming call ringing through your computer speakers.

This can help you hear incoming calls even when your headset is not being worn.

Note: Not every device or application version supports separate ringing and call audio outputs.
