It is legal to create connection without setting the destination ip and port (this usually done later through MDCX). However, if some other connection tries to deliver an RTP packet through a a half open connection, then the fact that no destination ip is set is logged as error even if it is a pretty normal situation. - Check if destination ip and port are set to zero. If yes, we assume that the destination connection details are intentionally not set yet. Only when one value is set and the other one not, we log an error. Otherweise we log a message to debug.

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
