Change subject: mgcp_client: add support for VND.THEMWI.CCSD codec ...................................................................... mgcp_client: add support for VND.THEMWI.CCSD codec TW-TS-007 defines a compressed RTP payload format for GSM CSD, reducing the payload size from 160 bytes of mostly constant filler bits to 16, 32 or 37 bytes depending on specific CSD mode: https://www.freecalypso.org/specs/tw-ts-007-v010001.txt Clause 9 specifies payload type number 127 when this pseudo-codec is used on AoIP interface, while Annex A gives it the name VND.THEMWI.CCSD for SDP. Add support for this codec to libosmo-mgcp-client, to make it possible for OsmoBSC and OsmoMSC to request this codec from MGWs.
