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.
