Answering machine

I have 4015 Gigaset base unit,our two handheld unts showing "line in use" even if we take the gord out and reset batteries from the unit.

Unfortunately the 4010 model does not have a built in answering machine but does have features to work with your local telephone companies voice mail. If you want to keep your same phones and get a base with a built in answering machine you will need to replace your 4010 base with a 4015 base (up to three handsets), or a 4215 base (up to four handsets). But don't toss out your old base, you can use it to extend your range if you ever use a 4200 series handset that will allow you to register each handset to up to four seperate bases simultaneously to extend the range. You can buy the 4015 or 4215 base only and save yourself some money. You can google Siemens cordless repair or go to the Siemens website to find a few options.
