Parse the endpoint index from the MGCP messages as base-10, not 16. If osmo-mgw parses the endpoint IDs as base-16 numbers while OsmoMSC and OsmoBSC pass in decimal endpoint numbers, the consequence is, for example: - I configure 32 endpoints in osmo-mgw, - I tell OsmoBSC to use endpoint range 1-32, - At some point OsmoBSC may pass in, say, "30@mgw", - "30" is parsed base-16 and ends up being endpoint index 48, instead of 32, - OsmoMGW sees that 48 > number_endpoints and barfs.

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. The libosmo-mgcp library exposes MGCP server utilities used by e.g. OsmoBSC-NAT (found in osmo-bsc.git) to navigate RTP streams through a NAT. (At time of writing, this is still called libosmo-legacy-mgcp.) Find OsmoMGW issue tracker and wiki online at https://osmocom.org/projects/osmo-mgw https://osmocom.org/projects/osmo-mgw/wiki
