Specifically, this means +there is no SIP REGISTER or any form of authentication supported. You +will need to configure the SIP peer to implicitly authorize the trunk by +its IP address / port. + +osmo-sip-connector handles only the signaling translation between GSM CC +and SIP, 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). Hence, **the SIP peer must support the +codec[s] you have configured on your MSC/BSC** + +As the osmo-sip-connector attaches to the external MNCC socket of +OsmoMSC, running osmo-sip-connector will disable the internal call +routing of OsmoMSC, see the related OsmoMSC documentation. All mobile +originated calls originating in GSM will be passed to the SIP connector. + Find the OsmoSIPConnector issue tracker and wiki online at - https://osmocom.org/projects/osmo-sip-connector -- To view, visit https://gerrit.osmocom.org/c/osmo-sip-connector/+/32002 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: osmo-sip-connector Gerrit-Branch: master Gerrit-Change-Id: Id42904a183b045eefac15a94139221a3bc65ecdd Gerrit-Change-Number: 32002 Gerrit-PatchSet: 1 Gerrit-Owner: laforge <laforge@osmocom.org> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: fixeria <vyanitskiy@sysmocom.de> Gerrit-Reviewer: laforge <laforge@osmocom.org> Gerrit-MessageType: merged
