Hi!

I suppose you need openssl libraries. But if you don't want to install openssl you can just replace pjsipdll.dll with pjsipdll_notls.dll. I've just added pjsipdll_notls.dll to the repository. Update sources again.

regards,
sasa

I've found the error!

It was a really stupid error! i was having an instance of SJPhone
running, so probably the bind to port 5060 fails!

(But what an error regarding memory access violation??)

Well thanks for your reply...
