The commissioning of the telephone set is easy. The description is very good, short and sweet, but it's all there, what you need. For me the phone to a home telephone system worked, as well as directly. Because the old house PBX phone number is not passed, then I have the phone connected directly and decommissioned the plant. For two persons in the household yes suffice the two phones. Only with the intelligibility of speech, I am not so satisfied, why only 3 stars
