Recommend any IOS app for making calls from multiple phone numbers from my 1 mobile device?

Does anyone know of any apps (preferably non VoIP) where you can add new phone numbers and call/ message from them? Example: I want to make all my business calls from a separate number, I want to use a separate phone number for dating / seller websites etc. Also the ability to add a fixed line or international number (+44, +1, +86 etc) for when dealing with foreign clients or I am within that country. The only app I know of to date is www.tizyo.com and https://www.vyke.com but Vyke is limited to 4 numbers and is VoIP. Thanks for any recommendations
