MDA Compact III Ending Call Sound

[Guest w1ld]

How do.

Even when my MDA Compact III is on silent/vibro mode, each time a call is ended (or more likely when it is ended by the other person first), the device beeps 3 times. I have been unable to change this via "Sounds & Notifications", and unable to locate the wav/wma file (as I could just delete it). That said, I haven't had time to go through all the sound files in the \Windows directory. I considered it could be a system beep - sounds more like a sound file.

Could somebody please advise on the filename, and/or a way of disabling this.

Ending a call when in a meeting and having to muffle the sound in my jacket pocket is not ideal! :)

Many thanks.
