Hi all, Thanks for providing a platform for disscussion on PJSIP.I alredy asked a question that which version of Visual studio will be compatible for me(currently I am using window7 and pjproject1.10) from which I got reply that version 2005 and 2008 will be helpful.But still I am having trouble on these two version of express edition and also visual c++-6.Can anybody tell exact edition and exact version what I will use so that I can compile with no difficulty??? Thanks in advance with regards pranab Bangalore
