Description

between osmo-bsc_nat and osmo-bsc, we employ some special MGCP tunneling via IPA multiplex, which is so far not yet supported by libosmo-sigtran. Adding this would be a requirement to use new osmo-bsc.git with osmo-bsc_nat.

Assigning this to neels as he's doing SCCPlite interop testing. After having completed native SCCPLite, it is getting time to test against the osmo-extended IPA multiplex of bsc-nat, where this issue becomes relevant.
