Hi, Since we are not able to implement Audio call functionality on symbian platform, we want to try it out using windows mobile platform. I want to know which version of windows mobile (2003 2nd edition, 5.0 and 6.0) is best supported by PJSIP stack. Thanks in advance Regards Saurabh Agarwal Now you can chat without downloading messenger.
