Summary:                    Asterisk not sending out RTP packets
Description: 
I have Kamailio with MediaProxy in front of Asterisk running, asterisk does
not need/nor have to deal with any nat issues. All it is seeing are public
ip addresses (somewhat, because this test environnement runs on amazon
ec2).

I'm debugging SIP packets and everything looks fine though, but Asterisk
is not sending any RTP packet to my RTP proxy. It is receiving packets fine
though. What is stopping Asterisk to send packets to my RTP proxy? Nat=no
in my sip.conf

In additionnal informations, you will find the asterisk console with sip
debug and rtcp debug. Looking at the SIP headers I would interpret that
Asterisk would have to connect to the RTP proxy right away and not wait
until a packet comes in.

Do you have a Zaptel timing source? A card perhaps that is not configured
or using ztdummy?
