A call agent may send a CRCX to create a connection in LOOPBACK mode but without specifiying the destination address. In those cases the MGW should deduct the destination address from the first incoming RTP packet. Unfortunately this is currently blocked by an OSMO_ASSERT that checks the current sa_familiy against the sa_family from the incoming packet. This makes no sense since the current sa_family is still uninitalized, which is expected and not an error since the code that follows will initalize it. It also makes sense not to access the osmo_sockaddr struct members individually but rather copy the address as a wohle. Since the event only happens once and since it is also somewhat special it makes sense to log the event as well. Change-Id: I2dbd6f62170a7f62e5287d04a4ee6716b8786c26 Related: OS#5123 |

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.
