Landline Phone Service questions, answered by experts

Yes, most services include signal testing and adjustments for optimal performance.

Connectivity failures, static interference, damaged wiring, and software glitches frequently require professional repair.

The length of coax cable can affect the signal. Coax cables and their connectors all have a small amount of electrical resistance, which means that the longer the cable and more connectors in the system, the weaker the signal strength. In most homes, the signal loss is tiny, but systems with coax cable lengths over 100 feet will likely experience signal troubles.

Types of networks include wired Ethernet for stability, wireless networks for convenience, and powerline networks that use a home's electrical wiring for data transfer. Choose based on your specific internet usage needs.

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.
