How to Connect VoIP to a Landline
By Iam Jaebi
Voice over Internet protocol, or VoIP, is a technology that allows you to make phone calls over a high-speed Internet connection. VoIP telephone service is an affordable option to standard home phone service as it provides one flat rate fee for local and long distance calling as opposed to variable rate calling based on how many calls you make. The key to connecting VoIP to a landline phone is using an Internet adapter device, which routes telephone calls through the high-speed Internet connection in your home.
Connect one end of the Ethernet cable to a free port on your router or high-speed modem.
Connect the second end of the Ethernet cable to the Internet port on the VoIP adapter provided by your VoIP service provider.
Connect one end of the phone cable to the phone port of the VoIP adapter, labeled "Line 1" or "Phone 1."
Connect the other end of the phone cable into the port on the phone you want to use.
Plug the VoIP adapter device into an electrical outlet. Turn on the device if it has a power button or switch.
Pick up the phone and verify that you have a VoIP dial tone.
- Ethernet ports and standard telephone ports look very similar but are different sizes. If the Ethernet plug doesn't fit into a port because it is too big, the port is likely for a telephone.
- Plug a telephone jack splitter into the VoIP adapter device to connect more than one phone for VoIP calling.
- VoIP service providers require service activation to use their associated VoIP adapters. Consult adapter documentation or contact your service provider for details.
