I have a customer that purchased an Avaya 3735 Dect phone, they need a base station (I assume based on my research), the issue I am running into is all of the listings online at the many stores that sell Avaya shows the newer R4 Dect stations and they are compatible with all of the 3700 series phones but the 3735 is not listed as one. Has anyone had any experience with the Avaya 3735 DECT Wireless IP Handset? I assume it will work like the old D100 dect phones and need a base station. I just don't want to order the wrong base station or maybe there is something I am missing and this model does not use a base station. Any info is appreciated.
