I am working on a custom embeded security system build on a Nexus 7 tablet. I would like to be able to automatically call my cell phone (later the 9-11) from my application. I don’t know if it is possible. My guess is, that it is in theory.
So, anyone have an idea on how to make an internet call from Android program on a tablet?
Would it be complicated?
Is there a webservice I could use?
Making an Internet call requires
Session Initiation ProtocolStack on your phone. This is available on Android phones with Gingerbread and above.There is a detailed guide on developer.android.com .
It has all the code you need to make a call on
SIP over wifi.If you need a completely working code you can use
Sipdroidwhose source code is open.
