[Plugin: Contact Form 7] Default values in text fields

I am using Contact Form 7 within a members area of my site.

I would like the fields in CF7 to show default values that the user has entered when he registered as a member.

The members DB table is the same as the WP table.

I was able to retrieve Name, first name and email adress in my Contact form, but not the phone number yet.

The plugin I use for Membership access is WP Members.

Any hint.

Thanks in advance
