Thanks for replying. I actually followed the advice of the last poster on that thread (http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/2011-September/013371.html) as that would make it simple to get updates from PJSIP. Though I have run into a strange problem. Linker is unable to find IPP libraries (I have IPP codecs enabled) with 64 bit compiler even though same worked fine with 32 bit mode??

There is no clear statement whether pjsip completely supports 64 bit windows across all modules (pjsip/pjsua etc). However i have been using PJSIP compiled using VS2010 x64 in production without any issues since 2011. Absolutely NO downtime !. Look at this thread for changes made to 1.10. Maybe it can help. http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/2011-September/013372.html On Wed, Jan 7, 2015 at 5:54 PM, Anshuman S Rawat <arawat at 3clogic.com> wrote: Hi, I am confused as to whether 64 bit port for PJSIP is available or not. PJSIP wiki says here (https://trac.pjsip.org/repos/wiki/Getting-Started/Windows#BuildingtheProjects <https://trac.pjsip.org/repos/wiki/Getting-Started/Windows#BuildingtheProjects> ) in point 6 that "Currently we are still encountering issues with 64-bit builds, therefore it is not yet supported." but in release for 2.2 says that support for Windows 64 bit has been implemented in ticket 1680. https://trac.pjsip.org/repos/milestone/release-2.2#SupportforWindows64bit <https://trac.pjsip.org/repos/milestone/release-2.2%23SupportforWindows64bit> https://trac.pjsip.org/repos/ticket/1680 Then I took PJSIP source from trunk (about 2 weeks old) and built it successfully using 64 bit compiler in VS2013. So is PJSIP 64 bit ready? If not, what challenges remain. We need 64 bit port for PJSIP so can contribute if required.
