In contrast to that, AoIP is standardized. So you can interoperate your osmo-bts-trx + osmo-bsc against antoher MSC that's not osmo-msc. Note that this usually requiers in-depth understanding of SIGTRAN as there are many configuration parameters to take into consideration. osmo-bts + osmo-bsc has been connected to MSCs of various vendors such as Ericsson or Huawei.
