Thank you Daniel, I'm currently looking into your suggestion.
If I insert my public IP under:
# - start RTPProxy:
# rtpproxy -l _your_public_ip_ -s udp:localhost:7722
# - option for NAT SIP OPTIONS keepalives: WITH_NATSIPPING
Must I also modify UDP part below:
#!ifdef WITH_NAT
# ----- rtpproxy params -----
modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7722")
or can I leave it as is.
I have 1 NIC running private to VSP and 1NIC Public facing...So my mind is telling me to
keep it as 127.0.0.1???
Regards
Pieter

Now the problem is that if you call in Number(a)161.161.252.20
<mailto:Number@161.161.252.20> is send to kamailio, kamailio then
sends it down to dispatcher IP and that PBX responds directly back via
rtp server to 161.161.252.20. The 161.161.252.20 IP is private and
cannot be reached from the cloud and vice versa . How do I get
kamailio to be the middle man between 161.161.252.20 and RTP
server(all traffic must go via the kamailio
server) Is there specific modules I must load.
You need to use an RTP proxy to achieve this. So yes you need to load extra modules and
configure kamailio for this proxying. If you take a look at
https://github.com/kamailio/kamailio/blob/master/etc/kamailio.cfg
and search for rtpproxy. The really really short explanation:
you need to call rtpproxy_manage for calls that you want to rewrite rtp for.
