Who owns the numbers that are assigned to me by UniTel Voice and can I port or transfer them?

With UniTel Voice you are not renting your number nor are you under any contract that locks you in. You are the valid owner of a toll-free and a local number as long as you are in good standing (i.e., there are no balances on your account). You can transfer both your toll-free and local numbers to another provider at any time – no strings (or fees) attached.
