Specifies a list of codecs supported by MCP for VRM recorder. This option is used to limit supported codecs on the RTP streams sent to the recorder. It is similar to the main "codec" parameter, except in this case, the codecs and order in the offer are dictated by the codecs negotiated on the inbound call legs. By restricting the codecs in this list, a streaming issue on recorder streams caused by lack of transcoding support could be avoided, where the recorder sends a SIP session refresh with an SDP that changes the codec priority order from the original MCP offer.
