Yes, you do not usually connect a phone line to a modem. Still, if you run a business that hinges on Voice Calling, you might have to get one. Also, if you plan on setting up a landline connection at home for your parents to use, connecting a phone to a modem makes sense.
But you simply cannot plug any phone into your modem. There are a few things to consider. Like, the availability of a voice plan, the number of ports on the modem, nature of the internet plan, type of modem, and so on and so forth. Yes, it can get tricky at times. But then, I am here to help and make it simpler for you.
The first thing to consider is the type of modem in play. You can have a standard cable modem or a DSL modem to work with. Regardless, setting up a voice plan for either of them isn’t that tricky. And I shall touch upon both over the next few sections. The process changes for each modem type but is still straightforward, nonetheless.
How to Connect a Landline Phone to a Modem?
Things to keep handy:
- Modem with a phone port
- Modem-router combo if the modem doesn’t have a telephone port
- Ethernet cables
- RJ11 Cable
- DSL cable for modem-to-wall connections
- Router, if the modem has fewer ports than expected
- A Voice-supported internet plan (From the likes of Spectrum, Xfinity, Verizon, AT&T)
Is everything ready? Let’s get your modem with phone line connection up and running in no time.
Scenario 1: You’ve a Cable Modem/Gateway
Step 1: Check whether the cable modem comes with a dedicated VoIP port or a port with ‘Line’ or ‘Phone’ mentioned on it.
Step 2: Also, check if the device you are using is a standard cable modem or a modem-router gateway.
Step 3: Ensure that the phone isn’t plugged into the power supply and then plug it into the phone port of the modem or gateway device using the RJ11 cable.
Note: If you only have one telephone to connect and two voice ports in play, use the Phone 1 port first.
Step 4: Plug the ethernet cables into the LAN port of the device and connect it with the modem and the PC, in case you are using a gateway device.
Once connected to the modem, you can get internet and voice access. And the PC connection is to take care of the configuration issues if any.
Step 5: Once every connection is in place, you can start using your landline telephone.
Note: For VoIP phones, you can establish ethernet-only connections with the router/modem.
Scenario 2: You’ve a DSL Modem
You should know that a DSL connection uses the phone wiring to offer internet. Therefore, it is appropriate for it to work better with a landline telephone.
Step 1: Pick a Splitter/Dual Port Filter and plug it into the wall jack or wall socket to get the DSL connection in the first place.
Step 2: Plug an RJ11 cable into the splitter and the other end into the rear panel of the DSL Modem.
Step 3: Plug another RJ11 cable into the remaining splitter jack and connect the other end to the landline telephone.
Step 4: Connect the DSL modem to the PC using an Ethernet cable to see if the configuration is correct or not.
Scenario 3: Fiber Modems/Routing Devices
Step 1: Pick a relevant FiOS internet plan that comes with a GPON port.
Step 2: In most cases, you will find a phone port right beside the GPON port.
Step 3: Connect the landline telephone to an RJ11 cable and plug the other end to the mentioned phone port on the fiber optic device.
Frequently Asked Questions
Yes, you can plug your modem into any phone line, provided it has a telephone port corresponding internet-voice plan. However, if you have a DSL modem with you, the port shouldn’t be a concern as the DSL port works well with any RJ11 cable and a phone socket.
Landline phone service ensures that voice is broken down into smaller acoustic waves, converted into electrical energy, and sent across to other phones where the electrical energy is converted back to sound. And this is also the basis for DSL connections. For IP telephony, voice data transmission is more of a packet-based system, adhering to the VoIP protocols.
Spectrum and Xfinity are the more popular cable service providers that offer voice plans as well. For DSL services, Verizon and AT&T steal the show.
Hooking up a landline phone to a modem seems straightforward. However, there are quite a few things to consider before you can pick a modem, router, gateway device, landline device, and even the voice plan of choice. You must understand that not every modem/networking device works on similar technologies. And this is what causes a difference in the rollout, availability, and usage of voice services.
