OsmoMGW

OsmoMGW, the Osmocom Media Gateway, is a Media Gateway for handling user plane (voice) traffic in cellular networks.

OsmoMGW supports the IETF MGCP (Media Gateway Control Protocol) for control from Call Agents, such as those present in OsmoBSC and OsmoMSC.

At the moment (October 2017), OsmoMGW only implements RTP proxy / RTP bridge type endpoints, to each of which two RTP connections can be established.

We are planning to add endpoint types for
  • classic E1/T1 timeslots (64kBps alaw/ulaw)
  • classic E1/T1 16k sub-slots with TRAU frames for classic BTS support
  • announcement/playout end-points
  • conference endpoints

OsmoMGW is the generalized version of an earlier much more special-purpsoe implementation called osmo-bsc_mgcp.
