Factors To Consider When Looking For The Best Modem With A Phone Jack

Voice Modem

Modem vs Modem Router Combo

When you register with your internet service provider, they will ask you whether you want a modem or a modem/router combo.

Understanding the different features of the two devices will enable you to make the right decision.

When you get a modem only, it is easy and cheaper to upgrade. Additionally, you have the freedom to upgrade your networking capability and replace the modem with a better, newer model when you want. It is also easy to set it up.

With just a modem you get better control over the firmware and settings which is essential for small businesses with a focus on vulnerability and security protection.

With the control that you have over the specifications of a modem, you get a more advanced and stronger model with better wireless performance for your whole home.

On the other hand, a modem/router combo is less expensive when it comes to buying and setting it up as most ISPs give you the combo as part of your monthly bill.

A combination unit requires only one power outlet, takes less room, and needs fewer cables and wires.

With a modem/router combo, your internet service provider has some control as they decide the best software for your modem/router combo.

The ISPs can also push firmware updates that they think will be good for your combo.

ISP Compatibility

It is important to you find a modem that is compatible with your internet service provider because if it is not, the modem will not work.

Below are internet service providers that allow third-party voice modems:

  • Suddenlink
  • Mediacom
  • Optimum
  • Comcast Xfinity

Here is a list of ISPs that does not allow third-party voice modems:

  • Wave
  • Spectrum
  • Sparklight (formerly known as Cable One)
  • RCN
  • Midco
  • Grande
  • Cox
  • Blue Ridge
  • Atlantic Broadband
  • Armstrong

Typically, every ISP shows the devices that work better with their services. To ensure that you get the level of internet service that you have subscribed to, it is recommended that you buy the recommended models.

DOCSIS 3.0 vs DOCSIS 3.1 Standard

DOCSIS is the telecommunications standard used by cable internet providers to transmit data.

Currently, there are two options available: DOCSIS 3.0 and DOCSIS 3.1. DOCSIS 3.0 is slower but more affordable while DOCSIS 3.1 is the newer and faster standard.

The choice between the two depends on various factors, but to simplify it, if you have a Gigabit internet plan, most ISPs will require you to have a DOCSIS 3.1 modem.

Some ISPs, like Mediacom, specifically mandate the use of DOCSIS 3.1 modems. You should note that this requirement refers to the modem used for your internet connection, not necessarily for phone services (VoIP).

However, the necessity for a DOCSIS 3.1 modem ultimately depends on how you choose to set up your network.

If neither of the previously mentioned cases applies to you, technically you may not need a DOCSIS 3.1 modem.

Nevertheless, it is recommended that you opt for a DOCSIS 3.1 modem. This choice ensures your modem is future-proofed for any infrastructure updates or speed increases that may occur.

Channel Bonding

When opting for a DOCSIS 3.0 modem, you should consider the number of channels it offers, denoted as Y×Z (for example, 16×4).

These channels indicate the bandwidth capacity supported by the modem, with the first number representing downstream channels and the second number representing upstream channels.

A higher number of channels translates to increased bandwidth capability. It is crucial to ensure that the modem you select has sufficient channels to meet the requirements of your current internet plan.

Inadequate channel availability can lead to the modem acting as a bottleneck, restricting your internet speed and preventing you from fully utilizing the service you are paying for.

Number Of Ports

When selecting a voice modem, it’s important to consider the number of phone jacks you require. Most voice modems come with two jacks, although some models may only have one.

In addition, if you opt for a DOCSIS 3.1 voice modem, you must take into account the Ethernet port. With DOCSIS 3.1 modems, the Ethernet port often becomes the limiting factor for the modem’s bandwidth.

Certain modems, offer a Port Bonding feature, which enables you to combine two 1-gigabit ports to achieve a single data stream capable of 2 gigabits.

Another superior solution is employed by modems like the CM2050V, which feature a single 2.5-gigabit port instead of two 1-gigabit ports.

This configuration ensures compatibility with internet plans offering speeds of up to 2500 Mbps.

Consequently, such modems are future-proofed and will remain suitable for many years to come. In summary, a faster Ethernet port corresponds to a better-performing modem.

Phone Modem FAQs

Can I Simply Plug My Phone Into Any Modem?

If you have a VoIP cable modem available, you can connect an analog telephone to the phone jack and utilize IP telephony services.

However, before proceeding, it is essential to verify the compatibility of the RJ-11 port and cable.

What Should I Do If My ISP Does Not Allow Third-Party Modems

In cases where your Internet Service Provider (ISP) doesn’t permit the use of personal modems, you are required to obtain a modem directly from them.

While this restriction might be disappointing, there are certain advantages to consider. Some ISPs, like Spectrum and Armstrong, provide modems to their customers at no additional cost.

Alternatively, ISPs such as Midco may offer the option to purchase a voice modem directly from them for a price of $199.

Is A Modem Router Combo or Separate Units Better? 

Deciding which option is better depends on your need and budget. Having a modem router combo takes away the need for buying the two separate devices, setting them up, and finding out the features that fit each unit as the ISP would know best.

Otherwise, if you want the freedom of customizing the settings of your internet device so that you can create your restrictions, limit certain access to your network, and have extra security, you can get a modem.

Final Words

Hopefully, you now have an idea of the different modem options with a phone jack that are available in the market.

No matter what your budget is or what features you want, you will find a modem that perfectly suits your internet needs.

From this guideline, our pick for the best modem with a phone jack is the Nighthawk CM2050V as it has room for a multi-gig port, makes the most of VoIP services, and comes with two RJ11 ports.

When it comes to compatibility, this modem works with Xfinity standard and voice internet plans.

However, if Nighthawk CM2050V is not the modem for you, there are other options from this article that you can select from.
