Osmo-sip-connector

Introduction

osmo-sip-connector translates between MNCC and SIP protocols. It allows a OsmoMSC based cellular network to be interfaced with external SIP telephony.

osmo-sip-connector handles only the signaling, but does not handle RTP. The RTP user plane is passed transparently from the MSC-colocated osmo-mgw to the SIP side. This also means that no transcoding is performed. The RTP streams contain whatever cellular specific codec you have configured your network to use for this call (FR, EFR, HR, AMR).

An external SIP-PBX server which supports SIP-Trunks is required.

The following graphs illustrate how the network components are laid out:

Binary Packages

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
