I can tell for CSipSimple ;). The option is not yet integrated to the application. It (should be) behind in pjsip but no ways to enable/disable it in the app yet (I'm not sure if it is in r944 but for sure it is in nightly builds). Since nobody asked me for these options, I didn't take time to add these options in the UI. If someone need it, I can add options so that you can do more tests.
