We simply added a set of #ifdefs DISABLE_VOIP around the calls to pjsua. Then in Xcode we defined a new "configuration" that includes DISABLE_VOIP - where the standard configurations don't include it. - "Get info" on your project - Click configurations - Duplicate "Debug" - While still in the Get info window, click "Build" - Add -DDISABLE_VOIP to "Other C++ Flags" Once you do this you can then easily toggle between voip/no-voip builds.
