Landline Phone Service questions, answered by experts

For the average home office, you should only need one line. It’s uncommon to need more than one business line for a small or starting business. The exception is for the hard workers who manage multiple businesses out of their home and want a separate line for each to keep everything separate. In that case, it’s relatively easy to add another line with VoIP, but significantly more expensive for an analog/hardwired phone system.

Regular software updates, checking for loose connections, and protecting wires from physical damage help prevent issues.

Phone wiring in modern homes is commonly used for landline telephones, internet connections, and network setups.

Professional installation or repair of phone wiring includes running cables, connecting jacks, and ensuring proper integration with existing communication systems.

Many VoIP solutions advertise themselves for a team or office, which can cost thousands of dollars. But if you look for small business VoIP solutions, you can find many that offer a single line fit for a home office or sole proprietorship. That can include companies like RingCentral, OpenPhone, and even Zoom—along with traditional phone service providers you may already be using.
