Head to [telnyx.com/sign-up](https://telnyx.com/sign-up)![Telnyx Developers](https://developers.telnyx.com/assets/icon-external-link.svg) to sign up for your free Telnyx account. It’ll give you access to our Mission Control Portal, where you can buy numbers, set up and manage SIP Connections and more.

### Buy a Phone Number[![buy-a-phone-number](https://firebasestorage.googleapis.com/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MKZPjv1Z2fsErGmpWh1%2Fuploads%2FYf3GaJHzHhblrDNX6ICB%2Ffile.svg?alt=media)](https://developers.telnyx.com/docs/v2/numbers/quickstarts/portal-setup#buy-a-phone-number) <a href="#buy-a-phone-number" id="buy-a-phone-number"></a>

You can search for, buy, and provision new numbers - all within the Numbers section of the [Opentact Portal](https://portal.opentact.org/).

Simply click on "Numbers", then either "Search & Buy Numbers" and follow the prompts.

Check out the [Advanced Number Search](https://dantonia.gitbook.io/test/telephone-number/advanced-number-search) for more specific number searches.&#x20;

### Create an Outbound Voice Profile[![create-an-outbound-voice-profile](https://firebasestorage.googleapis.com/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MKZPjv1Z2fsErGmpWh1%2Fuploads%2FqrR1NTv5t26mPJKnIH8Q%2Ffile.svg?alt=media)](https://developers.telnyx.com/docs/v2/numbers/quickstarts/portal-setup#create-an-outbound-voice-profile) <a href="#create-an-outbound-voice-profile" id="create-an-outbound-voice-profile"></a>

Select "[Outbound Voice Profiles](https://portal.opentact.org/app/outbound-profiles)" on the left-hand navigation menu, click "+Add New Profile" and set up your profile name. Add the SIP Connection you just created above, the traffic type, the service plan, and your desired billing method.

> You can also do this programmatically via our **RESTful API**. Check out our documentation for [Outbound Voice Profiles](https://developers.telnyx.com/docs/api/v2/outbound-voice-profiles)API.
