The initially merged IuUP API and implementation in libosmocore assumed that RFCI with ID was always in the position of its ID inside the list of RFCIs. This was the case for messages sent by ip.access nano3g as well as our own osmocom implementation. However it was noticed that other nodes from other vendors actually use other order, as allowed by the IuUP message format. Hence, we need to break the assumption and provide explicit ID information in the list. NOTICE: This commit implies an API change when using libosmogsm. However, the previous API was never available in any libosmogsm release, and only available in both libosmogsm and osmo-mgw master, so we are only breaking compatibility between different master versions, which is acceptable.

About OsmoMGW ============= OsmoMGW originated from the OpenBSC project, which started as a minimalistic all-in-one implementation of the GSM Network. In 2017, OpenBSC had reached maturity and diversity (including M3UA SIGTRAN and 3G support in the form of IuCS and IuPS interfaces) that naturally lead to a separation of the all-in-one approach to fully independent separate programs as in typical GSM networks. OsmoMGW was one of the parts split off from the old openbsc.git. It originated as a solution to merely navigate RTP streams through a NAT, but has since matured to a Media Gateway implementation that is capable of streaming RTP for 2G (AoIP) and 3G (IuCS) GSM networks as well as (still not implemented at time of writing) transcoding between TRAU, various RTP payloads and IuUP. The OsmoMGW program exposes an MGCP interface towards clients like OsmoMSC and OsmoBSC, and receives and sends RTP streams as configured via MGCP. The libosmo-mgcp-client library exposes utilities used by e.g. OsmoMSC (found in osmo-msc.git) to instruct OsmoMGW via its MGCP service.
