Quieten Asterisk Sounds


Is there any way of making the volume of the asterisk system lower e.g. Alison. When my phone is on maximum volume I get a nice loud volume on a call ? the only problem is that if I get a ‘all circuits busy’ message from asterisk it almost blows my ear off!

I want to set the volume of the asterisk prompts to the same level as I do on a call.

Any ideas anyone?
