Okay phone as a stand-alone unit. However, avoid multiple base stations.I purchased two base stations and an extra (third) cordless handset thinking that my home offices could also use these systems as an intercom. No so, each cordless unit can only register to one base station at at time. That means that the other base station will not be able to intercom a cordless handset that is not registered to it. Sound confusing? Maybe a little. The short of it is that I have 2 base stations and 3 cordless handsets and I cannot intercom completely between them.Otherwise, the system is okay. The cordless unit has a built in speakerphone, which is nice.
