Ok tried this but still is distorted;
Main Topics
Browse All TopicsHi,
I am trying to make a custom ringtone for the 7940 phones. I have found the ring tone in wav format (24 CTU) and converted it to raw using cool edit. However when I transfer it to the cisco system there is a problem playing the tone. It comes out of the phone all distorted.
I have checked the setting and it all appears OK.
Any help would be appreciated.

Sounds like maybe you are not making the RAW file to the right specifications:
* Raw PCM (no header)
* 8000 samples per second
* 8 bits per sample
* uLaw compression
* Maximum ring size 16080 samples
* Minimum ring size 240 samples
* Number of samples in the ring must be evenly divisible by 240
* Ring should start and end at the zero crossing
(Make sure your sampling, bits and compression are correct!)
