Changes/additions Required in Symbian Mobile dialer Repost

Hi, We have a Symbian dialer based on PJSIP. We want to add some new menu items in which application will make http post/get request to api and display the result data on dialer. All data will be returned in xml format from API. 1. Voucher refill (post the voucher number to API and show result returned on app ) 2. Refill History (Get the refill history from API by posting username and password.) 3. Callback ( post 2 phone numbers from input boxes to the api and show the result) 4. Add Volume Control Option 5. Make it compatible with 3rd edition and 5th edition phones Developer will be responsible for getting the application signed. You can use our code or if you have your own code that is also ok. We need full source code after completion. Payment will be done through milestone only. Thanks
