App to app voice call like Viber & Line in android [closed]

Question

Recently I am working on an application in which I have to implement application to application voice call and instant messaging like Viber and Line.

I did some R&D and got two methods to implement voice call.

1. SIP

   a. android.net.sip

   b. SIP API Classes and Interface

2. VoIP

But I am confused how to use it. How to Setup SIP server for my app on my own server and on what basis I will call my friends like I have 4 friends in my app contacts.I have to call second one, then what parameter should I pass to call him/her using SIP.

@Cati i have a google server dude,not a IIS7. – Bendy

you wanna use VOIP or SIP.? – Cati

SIP is native api so finally i decide to use SIP. – Bendy

have you checked CSipSample App.? – Cati

yeah....it crashes. and i don't want to use any lib.becuse i am working on a product.i'll do whole code by my own. – Bendy

Its same thing what you need.. its open source so you can use its code. it is also using SIP API Classes and Interface. – Cati

yeahh.. i knew that.but still,and right now my requirement is to write a server for my app first.client i will write later. so provide me some useful links for server. – Bendy

i want to integrate SIP protocol on my server like viber. i purchased server from google. – Bendy

You didn't see this. And If it is related to installing SIP or VOIP server, move your question here – Bearden

hey downvoters,please dont close this questions.this not that much broad you are thinking.i just want to know a basic server integration. – Bendy

I think the steps outlining how to use the native client will help you continue with your application. I found the following link to help you out: github.com/Metaswitch/clearwater-docs/wiki/… – Cannon

Answer 1

The Simplest way I can see to create an application like this would to have a backend database with a user login system, the create a table to hold IP addresses corresponding to the users in the database. This way you could have a function to update the devices IP upon logging in or periodically while online (currently logged in). This would allow a second device using the application to find the other devices current IP and create a VoIP connection between the two.

Things you would need to know: how to create a VoIP connection. how to query a database use mySQL or JSON parsing. how to set up a small database on a webserver.

Your question is far to broad to go into detail as those details may not be what you are looking for specifically and thus not worth explaining, but I hope this helps you to look in the right direction.
