asterisk users - Nov 2017 - PJSIP and Non Media Proxy

Please correct me if I am wrong. With PJSIP there is no way for Asterisk to
stay a OUT of the media path, while with the old SIP channel, using
directrtpsetup and directmedia, it just works. The issue I think is that
other servers do not accept reinvites or updates to redirect media, so
PJSIP will not be able to step out ever. Using the old sip channel, the 200
OK with SDP tells the calling side to talk direcly to the other side.
Is there a way to do this with PJSIP?

There is no "directrtpsetup" equivalent in PJSIP. Even in chan_sip it
was experimental and could break things depending on the codec payloads
in use.
