         ------------
 
         1. using the profile_name found, lookup the rate_name based
            on $hourofday in billing_profiles
            - the day may be split in maximum 4 periods
            - each day starts with hour 0 and ends with hour 24
            - rate_name1 defines the first interval after hour 0
            - rate_name2 defines the first interval after rate_name1
            - rate_name3 defines the first interval after rate_name2
            - rate_name4 defines the first interval after rate_name3
            When the hour matches an interval use the rate_nameX found
            to lookup the rate in billing_rates
            - if no record is found use the rate called 'default'
         2. lookup in billing_rates the record having same name found above
            and billing_rates.destination = $this->DestinationId
            - return an array with all the values to
            $this->calculateAudio() function that called us

         ------------
 
         1. using the profile_name found, lookup the rate_name based
            on $hourofday in billing_profiles
            - the day may be split in maximum 4 periods
            - each day starts with hour 0 and ends with hour 24
            - rate_name1 defines the first interval after hour 0
            - rate_name2 defines the first interval after rate_name1
            - rate_name3 defines the first interval after rate_name2
            - rate_name4 defines the first interval after rate_name3
            When the hour matches an interval use the rate_nameX found
            to lookup the rate in billing_rates
            - if no record is found use the rate called 'default'
         2. lookup in billing_rates the record having same name found above
            and billing_rates.destination = $this->DestinationId
            - return an array with all the values to
            $this->calculateAudio() function that called us
