In the scenario where you have multiple geographical zones I would suggest to
install a natbox in each zone. The subscribers would use that natbox as proxy
and the rtpengine usage in NGCP would be disabled for subscribers (or
completely). As the NGCP would see the subscribers with public IP, the nat
management would also be "disabled" and that signaling would be kept local.

This would allow you to keep the audio near the user when possible and do
the nat stuff there too. You would only receive the "real" signaling in the NGCP
system.

For the natboxes I would use kamailio+rtpengine or sems or ABC SBC. 


cheers,

Jon
