OsmoMGW, the Osmocom Media Gateway, is a Media Gateway for handling user plane (voice) traffic in cellular networks.
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.
Situation in a typical Osmocom cellular network¶
It is Planned to use OsmoMGW also from OsmoMSC like this:
Osmocom provides binary packages for several flavors of Debian and Ubuntu GNU/Linux on a variety of architectures (i586, x86_64, armhf, armv7l). Unless you are a software developer interested in developing on Osmocom, it is recommended you use those packages instead of building from source.
For more details see Binary_Packages
