Dissappointing performance. A single phone call can put this system out of commission for close to 2 minutes, bad luck if you are one of the other 3 lines trying to call. Annoying features include the accompanyment to the other 3 lines....if miraculously, someone does get through to the answering machine but doesn't dial an extension, or hangs up, the system holds on to this call and makes all extensions ring for 20 minutes. What do you call that, "bonus pain?" . This might be a good system for someone who gets one phone call per day,but its a recipe for disaster for anyone... no make that EVERYONE else: you (especially), your clients, your family. This phone inspires me to buy a real system before my return options expire. Run away.
