# IPNordic

> Connect your IPNordic phone system to Verbu. Verbu signs in as a SIP user, so you keep your number and your setup.

Is IPNordic your phone system? Then keep your number and your setup. Verbu signs in to your IPNordic solution as an ordinary SIP user — that is, an extension — and takes the calls you send to it.

## What you'll set up

Two things:

1. **A SIP connection in Verbu** — Verbu registers with IPNordic using a username and a password, just like an IP phone would.
2. **A rule in IPNordic** — so the calls you want the agent to take are sent to the extension Verbu is signed in to.

The number stays yours. Your existing phones still work. If you ever want to switch the agent off again, you just flip the rule back in IPNordic.

## Before you start

You need:

* Access to your IPNordic admin panel (or the contact details for whoever manages it on your behalf)
* The number you want the agent to answer on — usually your main number
* **A SIP extension from IPNordic** for Verbu — that is, a **username** and a **password**

If you don't have a free extension, create one in IPNordic or ask your IPNordic reseller for one. That's the "account" Verbu signs in with.

## Steps

<Steps>
  <Step title="Create a SIP extension with IPNordic">
    Create (or find) an extension in IPNordic that Verbu can use. Note down the **username** and **password**. These are the details Verbu signs in with.
  </Step>

  <Step title="Add the connection in Verbu">
    Go to **Phone numbers** in the dashboard and add a new **SIP connection**. Choose **IPNordic** as the provider.

    The domain fills in automatically with `sip.ipnordic.dk`. Leave the port on `5060`, and choose the transport IPNordic gave you (usually **UDP**).
  </Step>

  <Step title="Enter the username and password">
    Enter the **username** and **password** for the extension you created with IPNordic. Also enter your **main number** in the field, so the agent knows which number it's answering for.

    Save the connection. Verbu now signs in to IPNordic and is ready to take calls.
  </Step>

  <Step title="Send the calls to Verbu in IPNordic">
    Go back to IPNordic and point the number you want the agent to take at the extension Verbu is signed in to. This can be direct or through your existing call flow.
  </Step>

  <Step title="Save and test">
    Save in IPNordic. Call the number from your mobile and check that the agent picks up.
  </Step>
</Steps>

## Optional: hand off to humans during business hours

A common setup is "Verbu answers after hours, while the team takes calls during business hours". You have two options:

* **In IPNordic** — set a time-of-day rule that sends calls during business hours to your team and the rest to Verbu.
* **In Verbu** — let the agent take every call and use **Forwarding** to transfer it on when it makes sense.

Most teams start with the time-of-day rule in IPNordic because it's the simplest.

## Common scenarios

<AccordionGroup>
  <Accordion title="The agent doesn't sign in (the connection is red)">
    The username or password was probably typed wrong, or the extension isn't active with IPNordic. Check the details, and that the domain is `sip.ipnordic.dk`.
  </Accordion>

  <Accordion title="Calls go through but the agent says nothing">
    Usually a codec mismatch. Ask IPNordic to allow `PCMU` and `PCMA` (G.711 µ-law and A-law) on the extension.
  </Accordion>

  <Accordion title="Callers hear a busy tone">
    The rule in IPNordic isn't pointing at the right extension, or the connection in Verbu isn't signed in. Check both.
  </Accordion>

  <Accordion title="The agent picks up but immediately drops">
    Usually a firewall or an SBC between IPNordic and Verbu. Send a call ID to Verbu support and we'll match it against our logs.
  </Accordion>

  <Accordion title="I want to undo this and go back to the old setup">
    In IPNordic, point the number back at the old destination — for example a queue or a group. Calls will go straight back to your team.
  </Accordion>
</AccordionGroup>
