One Talk Mobile App
Download and Install

Download the One Talk mobile application to activate your service and use your business line from your personal smartphone or tablet.

Before you begin

Activation on a tablet requires a valid US address for E911 functionality.
When a new endpoint is added, a soft reset must be performed on any desk phone sharing a phone number with the mobile client.

Steps

  1. Download the Verizon One Talk app from the App Store or Google Play™ Store.
  2. Open the
    One Talk app
    .
  3. If presented, tap
    Get Started
     to accept app permissions.
  4. Enter the One Talk phone number and preferred name then tap
    Request PIN
    .
    Ensure the user assigned to the line has a valid email address in My Business.
    If an email isn't received the user should engage their IT team to whitelist this email domain: vzwmail@ecrmemail.verizonwireless.com
  5. Enter the PIN sent via email then tap
    Activate PIN
    .
    If you receive provisioning error (-23) when requesting the PIN, this generally indicates a data connectivity issue. Turn off Wi-Fi and try again. If the issue persists, contact Tech Support.
  6. From the Setup your Device & Profile screen, enter the info (e.g., Name, Company, etc.) then tap
    Next
    .
  7. Select the preferred calling mode:
    • App Calling
      : All calls are made and received through the One Talk app. Call quality is reliant on data connectivity and susceptible to congestion.
    • Call Through
      : All calls are made and received through the native device phone number, however callers see and interact with your One Talk number instead. This provides a higher level of audio quality.
      For detailed instructions on setting up this feature, refer to Set Up Call-Through.
  8. Set up basic Visual Voicemail service:
    1. Tap the
      3-line Menu
      .
    2. Tap the
      Voicemail icon
      , which places a call to the voicemail system.
    3. Follow the prompts to finish setting up Voicemail.
    4. When complete, a Voicemail icon displays.
