Numbers is where you will find all your numbers that are going through TRACK Pulse. This is where you'll see numbers that have been ported over and this is where you can purchase new numbers as well.
To get to Numbers: Configuration>Pulse Setup>Numbers
To purchase new numbers, you will click +Purchase where you can search local and toll free numbers that you want to buy. From there, or if you want to edit a current number, hit the green edit button toward the right of the number.
Once in a specific number's profile, make sure to assign the number to a campaign and call plan. This will help you capture more accurate data as you can assign that number to a specific marketing channel and assigning it to a call plan will tell TRACK where to push the call to.
