  • Buying Additional Numbers

  • Releasing a Phone Number

How Our VoIP Works

Acquire VoIP is built using Twilio and WebRTC. If you'd like to set up VoIP and SMS with your own Twilio account, read Setting Up VoIP & SMS with Your Twilio Account →

After setting up a number, you may assign it to a department. If you’d like incoming calls and SMS messages to route to all agents on your instance, leave the assignment field blank. 

Then press ‘Save’.

Only the department(s) assigned to the number will be able to make outgoing calls and replies using SMS messaging. You may assign IVR, routing, voicemail, forwarding and more in Business Rules for Phone Calls→

Buying Additional Phone Numbers

You may wish to add additional phone numbers to your account for:

  • Local presence across different geographic regions
  • Assigning numbers to specific agents or departments
  • Campaign association

We suggest purchasing numbers from Twilio and using our Twilio integration. If you purchased numbers through Acquire previously, reach out to our Support team ( to learn more about purchasing new numbers.

Testing Your Phone Number

From the Acquire Dashboard, click the phone icon.


A dialpad will pop up, allowing you to make calls or send text messages. Use the dropdown menu to select the phone number you want to call or message from. Click ‘Call’ or ‘Send SMS’ to complete the test. We recommend testing both channels before launching voice or SMS in your instance.

Releasing a Phone Number

Remove a phone number from your account by navigating to Settings > Installation and Setup > VoIP Settings. On the home screen, click the three dots (‘...’) under Actions for the phone number you’d like to release. A confirmation popup will appear, click ‘Release’ to complete the action.

Note: Releasing a phone number allows it to go back on the market to be purchased by another entity.
