Review on 📞 VTech DS6401 Accessory Cordless Handset in Black - Compatible with VTech DS6421 or DS6422 Expandable Phone Systems by Erin Ellis

This is a Vtech DS6401 extension phone, the only one that Vtech makes for use with the DS6421 system. At the time of writing, Revain listed the item as CS6401, but after being confirmed over the phone that it was a typo, I ordered four. They have arrived and look exactly like the phones that came with my DS6421-3 system. First impressions are that the system works well when connected to two iPhones. I haven't tried it with a stationary one yet. A downside is that some of the advertised features, like push-to-talk, only work on a limited number of phones. Vtech has published a guide online detailing these limitations, which cannot be found in the marketing literature. If I have anything to say, I'll post a review of the DS6421-3 system myself.
