If you need to make or receive a voice call in an area that has marginal cell service, you can still do so with your Android smartphone. Using your internet bandwidth, you can now make VoIP phone calls.
Voice over Internet Protocol technology (VoIP) is one way you can make phone calls even without traditional telephone copper wires. Especially if your network signal has been playing tricks on you, you can opt to use a VoIP by connecting to a WiFi network connection instead. In order to do this, you have two options to set up your VoIP. The first option is through the use of Session Internet Protocol (SIP), a signaling technology commonly used in commercial VoIP apps. Or you can also use Skype, the proprietary internet calling system. With the Skype option, you just need to download an app and create an account. The SIP option however, is complicated to set up.
Once you’re done with the set up, you can make calls anywhere as long as you’re hooked to a WiFi network. You can choose to go with one option but if something goes haywire, you’d be better off having the two installed already. You can use Skype for free but if you want better call quality, you can pay the $60 annual fee. SIP, on the other hand, has a free incoming number. Again, it may be difficult to set up the latter.
Again, using the information you obtained from Step 3, enter server or proxy data on the field labeled ‘Hostname or IP address.’ You can test the app by using the number your provider has given you for testing. However, there are some providers that don’t provide this.
Once you’re satisfied with the quality of service, you should purchase some minutes on the website. When done, try an incoming call test from a regular phone. Dial your IPKall number. Once successful your smartphone will ring using the Sipdroid interface.
To know that your Sipdroid has successfully connected to the server, look for the green notification tray dot on your phone.
