    Hi,
    I have a script working properly.
     
    But some users sad that voice volume is high and anothers sad that the voice is low..
     
    proc ActionPlayWelcome { } {
    puts "IT7: playing audio Welcome"
    global WelcomePrompt
    global CallerID

    leg setupack leg_incoming
    leg proceeding leg_incoming
    leg connect leg_incoming
    set CallerID [infotag get leg_ani]
    puts "IT7: Caller ID $CallerID"
    media play leg_incoming $WelcomePrompt
    puts "IT7: Audio played Welcome"
    }
     
    thanks.
