 h2. Introduction 

 osmo-sip-connector translates between MNCC and SIP protocols and hereby replaces the old LCR based approach. Osmo-sip-connector does not handle RTP by itself, an external SIP-PBX server which can accept SIP-Trunks is still required. The following image illustrates how the network components are laid out:

 h2. Manuals 

 Unfortunately, contrary to other Osmocom network elements, there is no user manual available yet at http://ftp.osmocom.org/docs/latest/ 

 h2. Howto (configure/run it) 

 See [[Howto]] 

 h2. Source code
