The BT 1700 Nuisance Call Blocker Cordless Phone with Answering Machine gives you back control over which calls you want to take and which you want to block. The BT 1700 can block 20 individual numbers, meaning that you really can avoid speaking to the people you don?t want to. For those times when you just want some peace and quiet, switch on Block All so that your phone won?t ring. If you want key friends and family to still get through, they can do, by tagging them as VIP?s in your address book. The cordless phone is packed with additional features including excellent sound quality, volume control, easy setup and a long range reception of up to 300m outdoors and 50m indoors. The phone provides up to 10 hours of talking and 100 hours on standby and allows you to see and hear if you have a second call waiting. You can also see who's calling before you pick up and the easy-to-read screen shows when you have messages. Save up to 50 contacts and redial any of the last 20 calls you made.
