Change outbound call number?

Hello,

I am trying to figure out how to forward everything from my work iPhone to my Galaxy Note 8 (which is no easy task). The provider for the work phone is Verizon.

I figured out how to forward my calls, but I was wondering if there is a way I could change my outbound calls to match that number when I want to. Are there any apps? I can't import it to Google Voice, but if there is an alternative app or method that doesn't require me having access to the account, that would be great. I don't see a Verizon equivalent to DIGITS, which would be perfect.

Any ideas?

Thanks!
