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.

a problem with your Zaptel configuration and will shutdown for your
protection.  You have options:
        1. You only have to compile Zaptel support into Asterisk if you
need it.  One option is to recompile without Zaptel support.
        2. You only have to load Zaptel drivers if you want to take
advantage of Zaptel services.  One option is to unload zaptel modules if
you don't need them.
        3. If you need Zaptel services, you must correctly configure
Zaptel.

"is used if available"; what if I take step http://bugs.digium.com/view.php?id=1
and compile without zaptel
support?
