Six days of house arrest down!

Lindsay Lohan was hangin' out on her terrace at her pad/jail cell in Venice on Tuesday with sis Ali, and it looks like she's doing some major business.

Lohan took a work-related call on her phone while also taking a meeting with some guys in business suits -- planning her next movie deal perhaps?

Lilo is confined to her residence for at least another 30 days, and we're really pulling for her to get through this arrest without a hitch.
