osmo-bsc_nat in its current form was written strictly for SCCPlite / IPA multiplex.

It hence doesn't understand the 3GPP AoIP protocol variant, and doesn't use libosmo-sigtran for interfacing with either BSCs or MSCs

In order to be able to use it also with 3GPP AoIP, we will probably need to

• make sure SCCPlite/IPA support in libosmo-sigtran is complete + validated
• port osmo-bscnat over to use libosmo-sigtran as transport interface on both BSC and MSC facing interfaces
• run an instance of osmo-mgw next to osmo-bsc_nat for handling RTP and OSMUX media streams to/from BSC and RTP to the (3rd party) MSC
