Ringer File
Custom ring tones can be uploaded to the phone.
The following file formats are supported:
•
WAV format. The recommended specifications are:
•
Audio format: PCM
•
Bitrate: 16 kB/sec
•
Sampling rate: 8 kHz
•
Quantization level: 16 bit

•
MP3 format (OpenStage 60/80 only). The OpenStage 60/80 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 con-
stant 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.
See the following table for estimated file size (mono files):

The file size for a ringer file is limited to 1 MB. If the file is too large or the contents
of the file are not valid, the file will not be stored in the phone. This limitation is only
enforced on WBM. If a ringer file is downloaded via OpenStage Manager, this restric-
tion does not apply.
