One Talk
Call a Number

Follow these instructions to make a phone call from your One Talk device, whether you're using a desk phone, a mobile phone or the One Talk mobile app.

Before you begin

Refer to this list of One Talk Supported Devices.
For billing purposes, Wi-Fi calls always originate in the US, even when you're outside of the US.
Wi-Fi calls to US numbers are not billed (except for 411 or other premium calls).
Wi-Fi calls to international numbers are billed according to your international long distance plan.
N11 calls including 211, 311, 411, 511 and 811 are not supported in call-through mode. In these cases, the phone's native dialer should be used.

Call from Desk Phone

  1. Enter the desired 10-digit number then press
    Send
    .
    Do not prefix the dialed number with a 9 as is currently required with a traditional PBX (Private Branch Exchange) system. If a 9 is accidentally added, the call fails and the caller receives an error recording.

    One Talk app

    within 10 seconds of the prompt appearing in order to connect the call.
    The number on the confirmation prompt doesn't replace the party you're trying to dial, but rather is an interim number used to help route the call. The called party will see your One Talk number and not the mobile number of the phone from which you're calling.
