I have disabled directmedia and directrtpsetup and it made no difference. I have even forced one endpoint to use GSM and the other to use ULAW (forcing asterisk to re encode everything) and asterisk STILL stops sending RTP when the endpoint does...

Asterisk doesn't have anything to send. What do you expect it to send 
when it's not receiving anything? I see that we have an rtpkeepalive 
configuration option, but I don't see that any code actually causes 
keepalive packets to be sent anywhere... it did when it was first added, 
but somehow that code has been lost.

This certainly warrants some investigation to find out when it was 
removed and why, because the configuration option should have been 
removed if the keepalive support was removed on purpose.
