silent ringtone for cisco ip phones

Unanswered Question
Feb 23rd, 2009

I am trying to create a silent ringtone (no music) for cisco ip phones based on the specs given below. What is happening is the phone accepts the raw file (from the edited distinctive ring list). For every ring, there seems to be a clicking sound. Is there a way to fix it?

PCM File Requirements for Custom Ring Types

The PCM files for the rings must meet the following requirements for proper

playback on Cisco IP Phones:

• 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 evenly divisible by 240

• Ring starts and ends at the zero crossing.

• To create PCM files for custom phone rings, you can use any standard audio

editing packages that support these file format requirements.

I have this problem too.

I don't see it in softkey template. Am I missing anything here? or is it only for IP Manager Assistant?

I was able to create a silent ringtone with 2 software and used it successfully on a few ip phones. Posting it in case someone needs it for their use.

actually it depends on the version, 6.x and above have DND as a standalone feature

previous versions do require IPMA to use DND
