AT%SPVER: new command for setting custom speech version lists The speech version list in the Bearer Capability IE tells the network which speech codecs are supported by the MS, and in which order of preference. The standard behaviour is to list all codecs that are supported by the hw+fw platform, and the standard preference order is newer over older, FR over HR. But sometimes it is desirable (for network testing) to artificially restrict which codecs the test MS will declare as supported, and/or to list them in some peculiar non-standard order of preference. Add a new private AT command, AT%SPVER, allowing the user to set and clear custom speech version lists for the Bearer Capability IE composer in CC.
