A user reports crashes of osmo-bsc upon EV_MDCX. It turns out that there is a lot of error reporting and a distinct possibility to get a NULL return value because of external input. Terminate the FSM instead. FSM termination is the proper way to report a bad error, it signals the parent_term_evt to the FSM parent, which will then be able to act on the failed MGCP operation.

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.
