Good morning Daniel,
If RTPEngine is on the same server as Kamailio (Asterisk being on another server), and RTP
traffic is sent to and from RTPEngine, then the provider only needs to whitelist one
IP-Address. I thought with RTPEngine that all RTP traffic would go through it and then it
would pass it on to the correct destination. Is this correct?
Thank you

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?
In what sense do they need whitelisting? In a common NATed solution where is no
white/blacklist needed. UA gets RTP endpoints from SDP, starts sending packets to ip/port
and the destination will send back packets to the source ip/port, the router/firewall will
just send this to the actual UA. I have yet to find an UA that cares about where the RTP
stream is coming from with regards to the SIP traffic.
