SIP Mobile Callback allows you using your favorite SIP Account of your own to make phone call without using VOIP on your mobile phone.
How it works? You configure the application with details of your SIP account and your phone number. Then you enter number that you want to call or pick it from your device contacts. The application first call your phone and then place call to the destination. Yes, it is that simple. You can find this option useful when your Internet connection cannot be used for reliable high quality VOIP call. SIP Mobile Callback only uses your Internet connection to exchange small data packets with sip.uno server in order to initiate and control the call.
These application can be also useful for users that live or travel in country where VOIP is restricted as it allows you save money without actually running VOIP on your device.
It might be tricky to use VOIP when you are behind strict firewall, SIP Mobile Callback will help here as well as it only using one single TCP port 443 that is always open.
Security considerations: Your account is secure as the app uses secure encrypted communication (SSL) with the server. Details of your account are not stored at the server and only used while you are connected.
