The variable number_endpoints is used as a length indicator for the array that contains the trunk endpoints at all times. When osmo-mgw is startet up, the variable is set and osmo-mgw will allocate the memory for the endpoints. However, it is still possible to manipulate the variable via the telnet interface. When the value is increased osmo-mgw might start using unallocated memory at some point. Store subsequent changes of number_enspoints in a separate variable in order to write them to the config file. The changes will then take effect after a restart. Closes: OS#2632 Change-Id: I3994af016fb96427263edbba05f560743f85fdd4
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
