I'm in the middle of integrating the PJSIP Python module into our test-suite and just noticed, after getting the 'Assertion failed: (!"Unsupported transport")' error message when I tried to select TLS as the transport type, that although there are configuration points in the pjsua Python module (which is misleading) there is literally nothing in the _pjsua.c code, which the pjsua module relies on, for TLS or SRTP. I haven't looked at the pjsua c code extensively and am wondering what people's opinions are in terms of the time it would take to implement or port the TLS and SRTP functionality into _pjsua.c and finish off the pjsua.py module. It's a shame the Python module isn't feature complete as it certainly is an excellent tool on a lot of levels.
