You can store phone numbers to reach the owner in DealMachine
You can edit those numbers if necessary!
Just open a deal and scroll down to the Owner Phone Numbers section.
Scroll the list of phone numbers to the right and click the number you want to edit.
Edit the number.
NOTE: If you don't see an edit option, that means the phone number came from a skip trace. It is not possible to edit results from an enhanced search. As an alternative to editing, you can always manually add new phone numbers to a deal.
