System Rates are used to bill outbound cost for each trunk and system
When a outbound call is made and trunk is used, system will search the trunk rate and see if there's a rate matched, if yes, then it will calculate the cost and cumulative to trunk cost and system cost.
Click to Rate Management → System rates will show a list of the current system rates:
if Prefix is “default”, the rate will match any number prefix
if Length is “0”, the rate will match any number length
the Team under System rates actually does not make sense
If no trunk is selected, the call cost will be cumulatived to system cost, but no any trunk cost.
Trunk under system rate has has nothing to do with outbound route, only used to calculate the cost of the trunk
Only when the trunk is used for outbound, system will find rates matched under the trunk and do accumulate.
