[L] Change in osmo-msc[master]: send + receive SDP via MNCC
by neels 07 Mar '23

07 Mar '23

neels has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-msc/+/31698 ) Change subject: send + receive SDP via MNCC ...................................................................... send + receive SDP via MNCC Transmit and receive full SDP information via MNCC, to accurately pass codecs choices between the call legs. In msc_vlr_test_call.c test_call_mt(), show that when receiving MNCC, the codec information in SDP overrules the Bearer Cap codec information -- we expect to still receive inaccurate Bearer Cap from e.g. osmo-sip-connector, because we have chosen to add SDP to MNCC instead of trying to fix the codecs represented in Bearer Cap. For internal MNCC, the MT call leg now knows which codec the MO has chosen and assigned. For external MNCC, osmo-sip-connector receives SDP about our codecs choices and sends it in SIP messages, and we also receive the full SDP information from the remote SIP leg. Update the SDP in codec_filter every time it is received, to always have the latest SDP information from the remote leg. CC MNCC | ---ALERTING--> | add local side SDP to MNCC msg | <--ALERTING--- | store remote side SDP | <--SETUP-RESP- | store remote side SDP | --SETUP-CNF--> | add local side SDP to MNCC msg | -RTP-CREATE--> | use codec_filter, add local side SDP to MNCC msg | <-RTP-CONNECT- | store remote side SDP There still is one problem: when initiating MNCC, we do not yet know the RTP address and port to be used for the CN side, because the CN CRCX happens later. So far we send 0.0.0.0:0 as RTP endpoint in the SDP, until the CN CRCX is done. A subsequent patch moves CN CRCX to an earlier time, adding proper RTP information right from the start.

[S] Change in osmo-msc[master]: [codecs filter] store BSS codec list from Compl L3
by neels 07 Mar '23

07 Mar '23

Attention is currently required from: neels. Hello Jenkins Builder, laforge, pespin, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-msc/+/30118 to look at the new patch set (#2). Change subject: [codecs filter] store BSS codec list from Compl L3 ...................................................................... [codecs filter] store BSS codec list from Compl L3 The initial Compl L3 happens long before we establish a CC transaction. Remember the Codec List (BSS Supported), so that we can feed the new codecs filter with it. Subsequent patches implement feeding the filter.

[L] Change in osmo-msc[master]: add codec_mapping.h,c
by neels 07 Mar '23

07 Mar '23

Attention is currently required from: neels, fixeria. Hello Jenkins Builder, laforge, pespin, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-msc/+/30114 to look at the new patch set (#2). Change subject: add codec_mapping.h,c ...................................................................... add codec_mapping.h,c Converting between different codec representations is confusing. This codec mapping provides a consolidated overview of all our codec representations, and how they match up. In particular, it adds the SDP codec representation repertoire, preparing the use of full SDP on the MNCC interface.
