MNCC<->SIP bridge; attaches to OsmoMSC to interface with external SIP VoIP telephony https://osmocom.org/projects/osmo-sip-conector
In case the MNCC server is crashing we need to release all calls, use the event emitted by the MNCC connection and iterate over all calls and call the release function.
Osmo SIP Connector ================== Simple utility to map MNCC to SIP and SIP to MNCC. The VTY interface can be used to make configurations. The code doesn't have any RTP or transcoding support. Call identities can be either the MSISDN or the IMSI of the subscriber.
