I want to use the sip for calling to pakistan, India and Bangladesh . i want a dialer like Platinum Dialer( you can find it on itunes,google play,etc) for that i have to use a soft switch like (itel switch ). How can i do all these things my own . How can i make a server for sip through which my is connected to make a call .

A common way to approach what you're trying to do is to use an application server that supports JSR 289 SIP Servlets. There are several on the market. A simple one that you can download for free for Java development purposes is the WebSphere Liberty server which can be downloaded from here: http://www.wasdev.net (SIP Servlet support is currently in beta). Note that Liberty can currently be used in production for small, single server deployments. Asterix is also a popular server for this. If you're looking for a cloud based trunking for PSTN federation from SIP check out Twilio's SIP trunking capabilities.
