the system allows for low and medium settings for incoming leads and how it parses information for duplicates. On low, the system finds an inordinate amount of duplicates. On medium, it will only match a duplicate if it has BOTH the same phone and email. So, even if the lead has the same phone and name, it will NOT match it on the medium setting if no email is provided. There needs to be some way to fine tune this. We've had to use the medium setting because of how many duplicates we were getting. This was preventing i-leads getting assigned after hours. Now, we have duplicate leads that don't show as duplicates.
