[SR-Users] Kamailio-5.3.3. NAT and RTP not working

[Pavithra Mohanraja]

Hi ,

Could anybody please give me the approach how to configure NAT in kamailio
IMS.

I have installed kamailio IMS in openstack environment which has private
ips for all four vms (each component in one vm). pcscf has one floating IP
attached. I have enabled "WITH_NAT" and configured rtpproxy .

when i make a call from outside of openstack using 2 zoiper clients with
outbound proxy keeping floating ip of pcscf, I am getting 200 ok with all
SIP packets correctly flowing but there is no RTP Packet.

When i try the same within openstack environment without using public ip, I
am getting RTP Packets.

Kindly tell me the procedure of NAT Enablement or do i need to do anything
other than this.

Kindly help because i am stuck with this for long time.


Thanks.
