The VTech CS1551 DECT Cordless Phone features Call Blocker and an innovative dual-charging design which allows users to charge the handset face-down or face-up. Forward facing allows easy viewing of the display, while rear facing can be convenient for easy placement and retaining the overall sleek design. When you're not availble, the answering machine helps you answer the call and deliver the message to you afterwards with the 15 mins. recording time. You can store 20 calls and see who is calling with caller ID/ call waiting, displayed on the handset with the name, number, time and date of incoming calls. 3-way conference call is also available with up to 13 hours talk time to keep your meetings going.
