With all the Gigaset products being sold, there's bound to be some older equipment in the stores. There's also a good deal of old and used product being sold on the internet. The Gigaset 2420 and the cordless handsets have been revised several times since the inception of the Gigaset products in the U.S. The following will assist you in determining which handset or desk station you have and/or need. I hope this helps!
