Summary:                    RTP gets passed on without early media session
Description: 
When Asterisk sends out an INVITE and receives a provisional response
without SDP, it still passes on RTP packets arriving on this leg to the
other leg of the call getting established. As a consequence, Asterisk does
not generate ringing to the Zap side on the other leg, or it sends out a
183 response to the other leg. 

Discussion about this problem on the list can be found here:
http://lists.digium.com/pipermail/asterisk-dev/2008-January/031660.html

A SIP trace is not needed as it does not show anything unusual. 

Expected behavior is, that Asterisk should drop those RTP packets arriving
without an early media session established.

Do not pass audio until the remote side has indicated they are providing
early media, or if the channel has been answered.
