1. Create your VoIP account on Zoiper 3

Note: Visit https://oem.zoiper.com for more information about providing your users with a preconfigured/pre-provisioned Zoiper. This will allow the end user to bypass all the configuration steps and set them up to make calls immediately after they finish installation.

  1. Download and install Zoiper and run the software.

  2. If you have a business license, follow these steps. If not, move on to step 3.

    1. An activation screen will appear when you first run Zoiper. The first step is a login screen. Log in with the email address you used to purchase your Zoiper license and the password that Zoiper emailed to you immediately following purchase.

    2. Activating online: click the Activate online button and Zoiper will do the rest. .

    3. Activating offline: There may be circumstances where you can't activate online, such as a firewall or other security settings blocking activation. In this case, click the Activate offline button. This will generate a file named Zoiper<ComputerName>.certificate that contains information about your version of Zoiper and some details about your computer. You can find the certificate folder at ~/.Zoiper.

    4. Send the Zoiper<ComputerName>.certificate to register4@shop.zoiper.com who will send you back a certificate back.

    5. Save this certificate in the same folder as 2.c.

  3. You can now create your VoIP account on your new Zoiper softphone. Click on the Settings menu and select Create a new account.

    Zoiper Account Creation page.
  4. The wizard will ask you what type of account you want to create. You'll need to select SIP here, as Telnyx doesn't support IAX or XMPP. Click Next.

2. Troubleshooting

If Zoiper is unable to configure your account, make sure:

  • The server hostname is correct, and exists (Check spelling and periods versus commas etc.)

  • The username or password is incorrect.

  • The server is not responsive for some reason.

  • A firewall or other security settings are blocking access. See Step 2 for the option to activate offline.

  • The account needs additional configuration work in order to be registered.

If you've verified all the information is correct, you can save the information and complete the remainder of the configuration manually. To do this, select the I know what I am doing, save this information anyway radio option and click NEXT.

Account Wizard.

That's it, you've now completed the configuration of your Zoiper 3 softphone client and can now make and receive calls by using Telnyx as the SIP provider.
