Yealink MP54 IP Phone - Corded - Corded - Desktop - Classic Gray

Our IT guy said that TEAMS was the way to go, including moving our phone lines over there. That all happened with only a few bumps in the road, However these phones are very close to worthless for doing any business. First of all in the different categories that Amazon asks for review. Sound. NOT NEAR LOUD ENOUGH. A/B testing with other Yealink and phone system phones, the sound is low and distant and only works in an absolute sound free environment. SCREEN... the different choices on the screen are TINY, so much that if you miss by 1/16th of an inch, you don't get what you want! The sub text size in exactly 1/16 inch high, it's like reading typing on a page 6 feet away. Trying to put one call on hold for another is successful maybe 30% of the time. But the biggest problem is that although the phones have been given total proprietary for data flow in our routers, and we are using very little other internet flow, a good percentage of the calls are choppy to the point of causing frustration on the part of our clients. Serious frustration. We call them back on our cell phones, where the calls are actually going over the WIFI internet and they are clean and perfect without interruption. We spent hundreds on these phones and would not even give them away to another user. SO VERY SAD and this is hurting our business every day.
