I loved having this for my little kids to be able to dial 911 or the grandparents whenever they wanted. I used it over a VOIP line. No sign of use. This British retro telephone is a 1960's style icon. It has been updated with modern technology to ensure it works on any standard home telephone line - It plugs into any standard phone socket for use with an original style mechanical ringer. Fitted with push buttons meaning faster, simpler dialing as well as a last number redial function, which is a useful feature to have. Features receiver volume control on handset and ringer on/off switch. Phone itself measures 6.00" W x 8.00" L x 6.00" H.
