Goal: to create a client for TalkFrog, low cost calls service.
TalkFrog is an internet-telephony service, which works on CallBack principles. Advantages: low cost calls, working without internet access, commands receive to server via SMS.
- call to the subscriber from the phone book, calls history or direct-in-dialing. System callbacks to the user and his subscriber, connecting them to the server;
- redirection, user sets up call divert from his/her number to a free number 8-800. TalkFrog cheaply diverts all incoming calls to a new number with saving the phone number of the calling one.
We carefully thought out all the consequences of setting screens. Restrictions, iOS- and SMS-settings are no longer a problem for the users.
