Maybe you have enabled direct-media on the Asterisk side?

Betreff: Re: [SR-Users] Struggling with RTPProxy and RTPEngine
The SIP traffic is working this way for me but I still see RTP traffic going directly from
Asterisk to the UAC, which means they need to whitelist asterisk IP. Am I missing
something?

Subject: Re: [SR-Users] Struggling with RTPProxy and RTPEngine
Why would the UAC need to 'whitelist' Asterisk?
Here's an example of an inbound call from Asterisk to a UAC with a sip proxy in the
middle.
Notice how the proxy mangles SDP in the 200 OK reply. Media will flow directly.
Not saying you shouldn't figure it out how to setup and use rtp proxies, just that
it's not a must in all scenarios, especially when you have a media gateway such as
Asterisk listening on a public interface.

Hello,
Yes, I don’t the UAC to have to whitelist the Asterisk Server. Everything works great
for SIP traffic and I want the same thing for RTP traffic, but I just can’t get rtpengine
to work (and I have tried many configurations).

Is there a particular reason why you'd want to involve an rtp proxy in your setup?
Considering Asterisk is facing a public interface, media can be set up to flow direct
between UACs and Asterisk.

If this is really your config you should change the offer to answer for
the answer part of the config. Either use rtpengine_offer and
rtengine_answer in the correct places of simply use rptengine_manage and
let the module figure out the right command.
I.O.W. you aren't giving any indepth info on your config.
