Hi,

I recently got a Kamailio v4.0.0 server up and running with Siremis v4.0.0 on a Debian Wheezy system with mysql as backend database . The Chat, file sharing ,audio and video services work flawlessly even behind nat and the same need to be incorporated in an app. I have configured rtpproxy and tls with self signed certificates. This is basically a test environment and we will install the same kamailio version with commercial certificates on a live hosted server.

Server side everything is working. Problem is on the development side. Our company is venturing into VOIP apps for the first time and trying to look at how to go about it. Firstly we would like to start with an android app and then move on to Iphone, Windows, Blackberry and Symbian app.

We need to know what is required on server side (any software to be installed or any configuration on kamailio or addition of modules) and client side ( which library and development environment to use) to make it work.  Lastly in terms of security what things I need to take care of in the server and app.

Best Regards,
