# Purchase a DID on VoIP.ms

Before placing or receiving calls, you must have **at least one active DID** (or multiple DIDs) on your VoIP.ms account.

If you already have active DID numbers on your VoIP.ms account, you may **skip this section** and proceed to trunk configuration.

3. Select a country and region you wish to purchase a DID in
4. Choose a specific number or numbers and click the **Oder DID** button

### Next Steps

After purchasing your DID number(s), proceed with trunk configuration:

* [Configuring VoIP.ms Register-Based Trunk](https://support.portsip.com/portsip-communications-solution/configuring-sip-trunks/voip.ms-sip-trunk/configuring-voip.ms-register-based-trunk)

Once the trunk is configured in PortSIP PBX, you can create inbound and outbound rules to begin making and receiving calls.
