Hi,
Can't figure it out when to use RTPproxy, i am forwarding everything to asterisk in seem to work without RTPproxy.
The scenario is like this: Softphone -> INTERNET -> Kamailio - > Asterisk (private ip)
Now it seems to work without any rtpproxy but is it ok?
It’s totally fine. Rtpengine is mainly used to also proxy rtp ie: public to private, etc. But if your asterisk is public, rtps will reach it, and you’re fine with it, go ahead

I should point out proxying rtps and having asterisk in a private network is better security-wise, since only kamailio can reach it and you control kamailio.

yes, if your asterisk has statically assigned (NAT-ed) public IP, then you do not need RTPproxy. RTP proxy required when both sides of the call do not have statically assigned (NAT-ed) public IP.

Another example of when to use RTPProxy / RTPEngine is:
SIP user -> router -> INTERNET -> router / firewall -> Kamailio (private IP) -> Asterisk (private IP)
Apart from the routers, all other equipments are private IPs, hence being NATed and requiring RTP Proxy / RTP Engine to forward RTP streams to the correct ports. As David Vilasmil points out, security wise, this is the best approach.... but it is a PITA configuring and making all the services work correctly.

I do have kamailio an public IP and another nic with private IP that connects to the Asterisk LAN.
@Sergey I tried that scenario with double NAT, and, it work it.
If i choose to go rtpproxy which modules should i load (nat_helper, nat_traversal, rtpproxy) ?

They serve a similar purpose, but they're unrelated products and rtpengine is not based on rtpproxy at all.

Try to make a call to the device behind double NAT (home WiFi router + carrier NAT).
