We spent 26 hours on research, videography, and editing, to review the top choices for this wiki. While home landlines are on the decline, the usefulness of these multi-line phones is on the rise, since many not only connect to traditional phone lines but also to smartphones via Bluetooth and to VoIP services. Thanks to these capabilities, they represent a cost-effective way to pull your communications together, whether for a busy home office or a small business. When users buy our independently chosen editorial picks, we may earn commissions to support our work.
