# Phone Numbers

> Set up phone numbers for your agents – SIP trunking and direct number purchase.

## Overview

For agents to place calls, they need to be assigned a phone number. SalesFrank manages all available numbers on the **Phone Numbers** page in the left menu.

## Import a Number (SIP Trunking)

You can connect an existing phone number to SalesFrank via **SIP trunking**. SIP trunking is a standard protocol that allows phone numbers from third-party providers to be integrated into a platform over the internet.

### What is SIP Trunking?

SIP (Session Initiation Protocol) is the protocol used to establish modern phone connections over the internet. A SIP trunk is essentially a virtual phone line that you purchase from a provider and then connect to SalesFrank.

## Buy a Number Directly *(Coming Soon)*

<Info>
  This feature is currently in development and will be available soon.
</Info>

In the future, you will be able to purchase phone numbers directly through the SalesFrank platform, without needing a separate SIP provider.

### Verification Process

Purchasing a number directly through SalesFrank requires a **company verification** for regulatory reasons. To do this, you create a **Regulatory Bundle**.

**Required information:**

* Bundle name
* Country
* Company name
* Company registration number
* Company website
* Contact person name
* Contact person email
* Verification documents (e.g., commercial register extract)

Based on this information, SalesFrank handles the company registration on your behalf. Once verified, you can purchase phone numbers directly through the platform.
