Hi Everyone... I successfully compile and run pjsip on Symbian OS S60 SDK. Everything working fine. But one thing is I can't route my audio output to earpiece I make deep googling about this and find that this is issue of APS of Nokia SDK, Not the issue of PJSIP. To route this we need to integrate APS to PJSIP which kill more energy I thing :). Now do you have any plan to resolve this issue(Integrate APS) and if yes then how much time it will required. Thanks for Cooperation... Best Regards...
