Hello,
I'm having trouble understanding how Kamailio keeps track of contacts when used as an outbound proxy. When using Kamailio as the registrar, contact information for each endpoint is generally stored in the locations table.
However, when Kamailio is used as an outbound proxy, the location table isn't used to keep track registrations. How then does Kamailio keep track of contacts when used as an outbound proxy? Is Kamailio able to do NAT pinging on clients behind NAT in this scenario?
Thanks,
Isaac
