| 7 | 85 | laforge | osmo-sip-connector translates between MNCC and SIP protocols and hereby replaces the old LCR based approach. 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). |

| 9 | 85 | laforge | An external SIP-PBX server which supports SIP-Trunks is required. |
