Yealink T40GThree lines, gigabit, the T4 build quality.

Why the T40G is on the catalog.

The T40G is what you buy when you want the T40P's three-line chassis but with gigabit ethernet. At $119, it lands $30 over the T23G (which gives you the same spec set on a T2 chassis). The pricing only makes sense if you are deliberately standardizing on T4 — same wall-mount brackets, same handset cords, same Yealink RPS template — across the whole deployment.

Where the T40G actually shines: standardization. If your office has 30 T46Gs on the executive and supervisor desks and you want the back-office desks to use a cheaper phone without breaking the uniform look, the T40G slots in. Same handset, same chassis color, same keypad layout — visually it just looks like a smaller T46G. For facilities where consistency matters, that uniformity is real value.

Where to skip it for a new deployment: the T33G at $0 difference gives you four lines instead of three, color screen instead of mono, and BLF-capable keys on a T3 chassis. Unless you specifically need T4 chassis matching, the T33G is the smarter buy.
