# Choose the right setup

> Work out whether you need a Verbu number, forwarding from your PBX, or a SIP connection to your existing phone system.

There are a few ways to get calls into your Verbu agent. The right one depends on where your phone number lives today, and how much control you have over your phone system.

## In short

## Choose based on your goal

## What customers experience

Whatever setup you choose, the customer calls the number they already know. The difference sits behind the scenes:

* With **Verbu as a softphone**, Verbu owns the number and sends the call straight to the agent.
* With **forwarding**, your current PBX forwards the call to a Verbu number.
* With **SIP routing**, your PBX sends the call directly to Verbu's SIP destination.

For the customer it should feel the same: the number rings, the agent answers, and the agent can pass the call on to a person when it makes sense.

## What to sort out first

Before you change anything, write this down:

* Which number should the agent take?
* Should the agent take every call or only some calls?
* Should calls still be able to reach the team first?
* Who has admin access to the PBX?
* Can the PBX send to an external number, a SIP URI, or both?

If you don't have all the answers, start with the number and who manages the PBX. Verbu support or your phone provider can help with the rest.

## Recommended order

<Steps>
  <Step title="Get the agent ready first">
    Set up the agent's greeting, knowledge, and forwarding. Test it in the dashboard before you send real calls to it.
  </Step>

  <Step title="Choose the call path">
    Pick a Verbu number, forwarding, or SIP routing based on the table above.
  </Step>

  <Step title="Set up simple routing">
    Start with a rule that sends all test calls to Verbu. Add opening hours, queues, and fallback afterwards.
  </Step>

  <Step title="Test with real calls">
    Call from a mobile, check that the agent answers, and check that caller ID and forwarding work.
  </Step>
</Steps>
