With improved latency, here are a few popular apps (for iPhone and Android) that make Wi-Fi calling practical:

    My experience is all application are the same. The difference is only that of user interface. We can select any application that we consider easy to use. However, free applications like google messenger should not be used because they offer very few facilities. Companies like skype are least focused on the security. With these applications, VoIP service is also important. Regular VoIP service providers like Axvoice, vonage etc. provide a sound data security system. However, The best way to select an app is to ask your voip service provider. The service provider will tell you which application works better with his calling solution.

  • Mobile Voip calls are becoming increasingly popular, and it will continue to grow and become an important corporate tool through the years
