    I don't think pjsip places a null terminator on the filled in string.  May need to get the result of the function and add it: replaces[res] = '\0'

I'm in the process of writing a testsuite test but am fighting with PJSUA at the moment. Since I am going on vacation for a couple of weeks, I felt I should go ahead and get this review posted now. You'll see a testsuite review go up sometime at the start of 2015. Happy Holidays!
