Phone of the Day: Vertical SBX 24-Button Digital Telephone at a Menswear Store in Chicago 

I spotted this Vertical Vodavi LG Nortel Ericsson digital telephone at a menswear store in Chicago.  You name the manufacturer because it has a ton of different brand names stemming from Vertical buying Vodavi and Vertical partnering with LG Nortel which became LG Ericsson.

This phone design is a digital set, although the manufacturer also offers IP sets.
