Changing The Ring Tone
PROGRAMMING (Ring Tone)
When a call is made to the DDC_VoIP telephone, the audible sound heard (ringing signal)
may be changed to an alternative tone or perhaps a voice message or warning alarm.
To change this tone, select the
Change Ring Tone
option, enter the access Password and
click ‘Enter’.
The ring tone sound file needs to be in the correct format. Wave and MPG-3 files etc. need to
be converted before it is loaded into the unit. Conversion programs are available that can do this,
CoolEdit pro is a good example.
The sound file used MUST comply with the following specifications:
"
The file length MUST not exceed 390 kBytes AND a maximum length of 48 seconds.
"
Must be 8000 bit/s sampling rate, Mono, PCM raw 8 bit format using muLaw codec.
"
Save the file with a ‘.DAT’ extension.
Once the file has been created, select Browse, and pick the file to be loaded, then click on the
Start button.
Within approximately 10 seconds the phone should response with a successfully update
message.
