I've been using Zoiper successfully with 2 Freshphone numbers.
I've now tried the Freshphone app but can't seem to find a way to add my second number?
Does The Freshphone app only support having one phone number?
Yes you can only provision one number/account at any one time with the FreshPHONE app. To use more you will need to use, Bria/Zoiper/Groundwire etc.
