In Logged Calls crm_case_inbound_phone_tree_view

I have enabled email_from

When i create a new line, i enter a new customer (by choosing 'create' not 'create and edit') after that enter the email id in the new field i enabled.

when i save the line , the email id (email_from) is not saved in the corresponding res.partner form(the entered email id is visible in crm_case_inbound_phone_tree_view)

how can i make it available in res.partners also?
