You wanna make calls from PC to PSTN lines? if so try with some SIP servers like asterisk..

does it work with GSM modem or not?

Put your own effort to search in google and find the right solution.. here people may direct you in some extends(Ex- installation issues, bug fix, configuration changes etc..) but they won't do the whole project for you. if you need any consultation on this area you better appoint a right person for you.

Tips:- Asterisk and Digium cards may help you to achieve your task..

i do not think that using others experiences is doing all project I just want the best suggestion not doing anything more .
any way thank you for your answer.
