# Voicelink SIP Setup (/docs/telephony/sip-voicelink)

> Connect a Voicelink DID to your OmniDimension agents over SIP. The host, port, and dial prefix are filled in for you, so you only pick Voicelink and enter your number.

Voicelink connects to OmniDimension over a shared SIP trunk. You set your
trunk and DID to route through OmniDimension in the Voicelink panel, then
import the number on the OmniDimension dashboard. The connection details
(host, port, and dial prefix) are applied automatically when you pick
Voicelink, so there is nothing to copy by hand.

## Prerequisites [#prerequisites]

* A Voicelink account with a DID and a SIP trunk
* Access to the Voicelink admin panel
* The DID number you want to use with your agent

## Step-by-step configuration [#step-by-step-configuration]

  
    ### Set the trunk to OmniDimension [#set-the-trunk-to-omnidimension]

    In the Voicelink panel, open **Voice Services → SIP Trunk Management** and
    edit your trunk. Under **Bot Configuration**:

    * **BOT Provider**: select **OmniDimension**
    * **Status**: set to **Active**
    * Leave **Peer Monitoring** enabled

    ### Route your DID through the trunk [#route-your-did-through-the-trunk]

    On the same trunk page, under **Call Routing Configuration**, add your DID
    to **Inbound Call - DIDs** (and to the outbound list, or turn on **Use the
    same DIDs for outbound calls**).

    ### Configure the DID routing [#configure-the-did-routing]

    Open **Voice Services → DID Call Routing**, edit your DID, and set:

    * **Status**: **Active**
    * **Inbound Call → Route Call**: **SIP trunk**, then select your trunk
    * **Outbound Call → Route Call**: **Only answer**

    ### Import the number to OmniDimension [#import-the-number-to-omnidimension]

    On the OmniDimension dashboard:

    1. Go to **Phone Numbers**
    2. Click **Import from SIP Trunk**
    3. Select **Voicelink** as your provider
    4. Enter a name and your Voicelink DID number
    5. Click **Import Number**

    The host, port, and dial prefix are set for you. You do not need to enter
    SIP credentials.
  

  Voicelink authenticates by our server's IP, so there is no username or
  password to enter. If your number does not connect after import, recheck
  that the trunk and DID are both **Active** in the Voicelink panel.
