Call tracking reports tell where customers were calling from, and which locations were contacted. This information can be quite valuable, especially if you have multiple locations.
Getting a lot of calls from a certain area? Call tracking reports can tell you which location they are reaching. The reports can also provide valuable insight as to where you may want to put your newest location.
Call tracking will also help determine peak calling hours. With this information, a business can dedicate staff members during these peak times. Are a lot of calls coming just before closing time? Perhaps hours should be shifted to avoid dead time.
