Landline Phone Service questions, answered by experts

The phone jack is the square wall-mounted plate into which a telephone plug is placed for the phone to get service. You’ll know your phone is properly connected to a working phone jack if you hear a dial tone when you pick up the phone. Phone jacks are often silver, white, or beige and are usually located in the living room, kitchen, bedrooms, or dens. 

As long as your landline is corded, meaning your telephone has a handset wired to a base unit on the wall, it will work during a power outage. Cordless phones won’t work without power, and cell phones will run out of battery eventually, so having a corded landline can be vital if your area loses power frequently or for long periods.

It’s a good idea if you receive regular calls from customers, clients, or other important contacts. If phone calls are a daily occurrence for your business, no matter the field, then a separate business line will help you keep things organized. It also gives your business a more professional appearance, improves the security of sensitive business information, can help you manage costs more accurately, and may even be a good idea on the legal front.

Yes, many repair services include upgrading outdated systems with modern features.

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.
