Two employees are using Zoiper to forward calls from their VOIP phones to their iPhones. The owner wants the other 18 employees to use it as well. Do I need to buy licrenses for that or can they just download the free app from the App Store.
The call transfer functionality is part of the Zoiper Premium/ Gold packages. With Zoiper free you will be able to make or receive calls, but not make any call transfers.
