How do I control whether voice messages are played automatically?

By default voice messages are played as soon as they are received.

On a Windows PC / Mobile this can be changed by unchecking Beep on new messages in settings . If this is enabled voice messages will automatically play when received and vice-versa.

File / Menu ---> Settings ---> General and select Beep on new messages

On the Symbian version of Palringo to disable auto-play uncheck the following option.

Options ---> Settings ---> un-tick Play all new voice messages automatically

In addition, the Windows Mobile and Symbian versions will not play voice messages when in a 'vibrate' or 'silent' profile.
