phones are able to play MP3 files from 32 kbit/s up to 320 kbit/s. As the memory for user
data is limited to 8 MB, a constant bitrate of 48 kbit/sec to 112 kbit/s and a length of max.
1 minute is recommended. Although the phone software can play stereo files, mono files
are recommended, as the phone has only 1 loudspeaker.

enforced on WBM. If a ringer file is downloaded via OpenStage Manager, this restric-
tion does not apply.
