( https://gerrit.osmocom.org/c/osmo-bsc/+/41631?usp=email ) Change subject: MGW control: migrate to new API for fmtp ...................................................................... MGW control: migrate to new API for fmtp Some codecs have additional parameters that need to be communicated to the MGW using fmtp lines in SDP. We use this mechanism to indicate octet-align=0|1 for AMR and signal the use of TW-TS-001 and TW-TS-002 extensions for FR/EFR and HR, respectively. Migrate from legacy struct mgcp_codec_param (now deprecated) to the new fmtp string API.

MGW control: migrate to new API for codecs and payload types struct mgcp_conn_peer in libosmo-mgcp-client API used to have a mandatory codecs[] array for codec specification and an optional ptmap[] array to be used only when the default payload type needs to be overridden. But now the codecs[] array is deprecated, and new API features (see following patches) require the use of ptmap[] array, with mandatory specification of payload type by the MGCP client. Convert osmo-bsc to this new API.

[S] Change in osmo-bsc[master]: E1: add support for AMR in TW-TS-006 enhanced RTP format

( https://gerrit.osmocom.org/c/osmo-bsc/+/41632?usp=email ) Change subject: E1: add support for AMR in TW-TS-006 enhanced RTP format ...................................................................... E1: add support for AMR in TW-TS-006 enhanced RTP format AMR speech codec on E1 BTS is currently possible at all only with tw-e1abis-mgw and not with classic osmo-mgw. This new E1 AMR MGW support includes all 3 possible RTP formats from the beginning: RFC 4867 BWE, RFC 4867 OA and TW-TS-006 OAX. Because TW-TS-006 is non-standard outside of GSM networks specifically built with Osmocom+ThemWi hybrid stack, use of this RTP format has to be explicitly requested by the CN via BSSMAP extension of TW-TS-003, which OsmoBSC already understands. Add TW-TS-006 to the set of supported RTP extensions with E1 BTS, joining already supported TW-TS-001 and TW-TS-002.

[M] Change in osmo-mgw[master]: mgcp_client: add fmtp string to struct ptmap

Credit: this patch is a derivative work based on Neels Hofmeyr's patch If58590bda8627519ff07e0b6f43aa47a274f052b from WIP branch neels/sdp, reduced to just libosmo-mgcp-client. Present necessity: this functional addition is needed in order to allow osmo-bsc to pass this construct to its MGW when the CN requested the use of TW-TS-006 extended payload format for AMR: a=rtpmap:112 AMR/8000/1 a=fmtp:112 octet-align=1; tw-ts-006=1 AMR codec fmtp parameter tw-ts-006 (defined in TW-TS-006 spec section B.1) is not supported by osmo-mgw; however, it is supported by tw-e1abis-mgw, which is the OsmoBSC-compatible MGW needed for E1 BTS with AMR and CSD.
