Review on Enhance Your Communication with the Grandstream HT801 Single-Port Analog Telephone Adapter by Maurice Ford

This adapter should have been new. However, when I tried to install it, I immediately encountered problems. When I contacted my VOIP provider, the first question was whether I bought it used because the MAC address was already registered in 2017 for another customer. For those not in the know, the MAC address needs to be unique. So I couldn't use this adapter. Either the device has been refurbished or the manufacturer is using MAC addresses again. In any case, this is unacceptable. I bought it on Best Products Prime. I don't know if the seller knew about these problems or not. To be honest I didn't rate the seller.
