10 Best Cable Modem With Phone in 2026

Its main strength is the combination of fast internet capability and voice functionality. A single Ethernet port can deliver true multi-gig performance to a compatible WiFi router, desktop, or other network device. Voice service includes features such as caller ID, three-way conference calling, and call forwarding, making it a practical choice for Xfinity subscribers who still rely on home telephone service.

The trade-off is that this is not an all-in-one WiFi system. You must connect a separate router if you want wireless coverage, although doing so allows you to choose WiFi 6 or WiFi 7 equipment and place access points where they are needed. Compatibility is also restricted to Xfinity Internet and Voice in the United States; it will not work with Verizon, AT&T, CenturyLink, DSL, DirecTV, or DISH.

This is our editor's choice because it addresses both sides of the category without forcing you into a dated DOCSIS 3.0 modem or a slower one-port Gigabit design. Buy it if your Xfinity plan is sufficiently fast, you need two phone lines, and you already own or plan to buy a capable router. For a comprehensive review of this product, you can also check out the top-rated options in our guide to the best cable modems for Xfinity.

Overall, the CM2050V is most attractive when your goal is to prepare for multi-gig service while retaining integrated voice. If your plan is much slower, paying for extra capacity may not produce faster real-world results, but the model remains a forward-looking option for growing Xfinity households.

Fast Wired Performance for Modern Networks

The 2.5 Gbps Ethernet port allows the modem to take full advantage of compatible high-speed internet tiers. Pairing it with a current WiFi router also prevents the modem's Ethernet interface from limiting a fast fiber-like cable plan.

Practical Xfinity Voice Integration

Two telephone ports and common calling features let the CM2050V consolidate internet and voice equipment. It is a sensible solution for subscribers who need traditional calling without adding a separate voice gateway.

As an all-in-one device, the CAX30 offers up to 2.7 Gbps combined wireless performance, coverage for as many as 25 or more connected devices, and four Gigabit Ethernet ports. It is approved for Xfinity plans up to 800 Mbps, Spectrum up to 1 Gbps, and Cox up to 1 Gbps. That provider flexibility makes it useful for households prioritizing internet and WiFi over telephone service.

Its DOCSIS 3.1 OFDMA technology is intended to improve response during congested periods, while the Nighthawk app assists with setup, guest networks, device pausing, and speed tests. Security features include WPA3, firewall protection, denial-of-service prevention, and an optional NETGEAR Armor trial. These tools improve everyday management, but none adds voice functionality.

Choose the CAX30 if your provider does not offer or require a bundled voice plan and you want one box to handle cable internet, routing, and WiFi. Do not choose it for Xfinity Voice or another traditional telephone package. Its value lies in convenience and broad provider support, not phone integration.

One Box for Modem and WiFi

Combining a DOCSIS 3.1 modem with an AX2700 router reduces the number of devices connected to your coaxial outlet. It is particularly convenient for apartments and straightforward home networks that do not need a separate access point.

Provider Flexibility and App Management

Compatibility with several major U.S. cable providers gives the CAX30 broader internet appeal. The Nighthawk app simplifies common tasks, although an active internet connection is required for full remote management features.

Four Gigabit Ethernet ports support wired computers, game consoles, streaming devices, and other Ethernet-capable equipment. On the wireless side, the router includes power amplifiers and AnyBeam beamforming on both 2.4 GHz and 5 GHz bands. Those features are intended to improve range and help maintain usable connections in larger homes with several connected devices.

The largest trade-off is its DOCSIS 3.0 foundation and lower supported plan tier compared with the newest DOCSIS 3.1 choices. It is also sold as a renewed product, so appearance or prior-use details may vary. A backup battery for keeping calls available during a power outage is also not included with this model.

The MT7711 is best for an Xfinity subscriber who wants internet, wireless networking, and two-line voice service in one box without a very fast internet tier. It can also make sense for backup or secondary use because of its three-function design. If your current plan exceeds its supported speed, choose a DOCSIS 3.1 modem instead.

Three Functions in One Housing

The MT7711 reduces the number of separate boxes needed for Xfinity internet, home WiFi, and telephone service. That convenience is especially valuable in spaces where every connected device and cable must be accounted for.

Flexible Wired and Wireless Access

Four Gigabit Ethernet ports give high-speed devices a dependable wired route, while dual-band WiFi handles phones, tablets, and laptops. The router's amplifiers and beamforming are designed to improve coverage without changing the basic service tier.

The T25 focuses on the core gateway functions rather than combining every networking feature in one enclosure. Its two Gigabit ports provide practical wired flexibility for a router and a directly connected device. DOCSIS 3.1 also provides a more modern foundation for current cable tiers and includes support for OFDM-related network efficiency improvements.

Setup involves plugging in the modem, downloading the SURFboard Central app, and following the activation process. The supplied information notes that a WiFi router should be connected for networking. Its two phone ports make it more directly relevant to the keyword than most standalone modems, although it is still limited to Xfinity Internet and Voice service.

This model makes the most sense for Xfinity subscribers with an internet plan up to 800 Mbps, two-line voice needs, and a separate WiFi router. It is less suitable for multi-gig subscribers, those who need built-in wireless networking, or anyone outside the Xfinity ecosystem. Its straightforward design makes it easier to recommend when voice and internet are the only priorities.

Modern DOCSIS Foundation

DOCSIS 3.1 gives the T25 a current cable-network platform and headroom for plans beyond basic Gigabit service. Actual performance still depends on your Xfinity plan, network conditions, and connected devices.

Two Ports for Each Core Function

Two Gigabit Ethernet ports and two voice ports provide enough connections for a router plus a wired device, alongside a conventional telephone setup. The design is simple, but its limited Ethernet speed makes it less future-proof for multi-gig plans.

Internet capabilities cover approved plans up to 800 Mbps on Xfinity and 500 Mbps on Cox. Four Gigabit Ethernet LAN ports support computers, consoles, streaming players, and storage devices, while the router offers up to 1.9 Gbps combined across both wireless bands. Beamforming is included to improve range and reduce dead spots.

This is a capable internet gateway, but it does not satisfy the voice portion of the cable modem with phone category. The absence of telephone ports means Xfinity Voice subscribers need one of the explicitly voice-enabled models. Its WiFi 5 platform is also older than the WiFi 6 option in this roundup, even though it remains useful for many connected-device mixes.

Choose the C7000 for straightforward internet and wireless service in a home that does not need traditional telephone support. It is appropriate for Xfinity and Cox subscribers within the approved plan ranges who want fewer boxes and easy app-based control. If voice is a requirement, skip this model and compare the CM2050V, CM1150V, or another Xfinity Voice option.

Convenient Two-in-One Design

The C7000 combines internet modem and router functions in a single unit, reducing shelf space and simplifying basic installation. It remains especially attractive to households that do not plan to use a separate mesh system.

Good Connectivity for Mixed Devices

Four Gigabit Ethernet ports and dual-band AC1900 WiFi support many common household devices. Security features include WPA/WPA2 encryption, double firewall protection, denial-of-service prevention, and automatic firmware updates.

Its primary Ethernet connection is a 2.5 Gbps port, supplemented by two 1 Gbps ports that can be link-aggregated for up to 2 Gbps of combined wired throughput. Mid/high-split technology, DOCSIS 3.1 Active Queue Management, and OFDMA are intended to support low latency and stable performance during busy periods.

The CM3000 supports major U.S. cable providers and remains backward compatible with DOCSIS 3.0. It does not support bundled cable-voice plans, however, and has no built-in WiFi. You will need a separate WiFi 6E, WiFi 7, or mesh router if you want wireless service, making the total setup larger than a combo device.

This is an excellent choice for fast cable internet users who do not need home telephone service. Its speed ceiling and port design make it a strong match for demanding homes, gamers, large downloads, and heavy simultaneous use. If Xfinity Voice is essential, the CM2050V offers a more direct combination of multi-gig speed and two-line calling.

Built for Fastest Cable Tiers

The CM3000's mid/high-split support and 2.5 Gbps Ethernet port remove bottlenecks found in older Gigabit-only modems. It is best used with a router or computer capable of handling the faster connection.

Low-Latency Network Management

Active Queue Management and OFDMA can improve response during congestion. These technologies are valuable in busy homes where gaming, video calls, streaming, and remote work overlap.

Four Gigabit Ethernet ports support computers, game consoles, and other wired equipment. Voice over IP is available through two telephone ports, while an optional battery backup can preserve calling availability during a power interruption. The product is therefore not only a convenience-focused router but also a credible choice for households that consider telephone continuity important.

Its main limitation is the older DOCSIS 3.0 platform and lower plan ceiling. Newer DOCSIS 3.1 models provide a better foundation for current and future cable tiers. The integrated WiFi also uses WiFi 5, so a large home or advanced wireless user may eventually want a newer router or mesh system.

The C7100V is a good choice for an Xfinity household with moderate speeds, two lines, and a preference for one integrated box. It is less suitable if your service plan is very fast, your home needs modern WiFi 6 or WiFi 7, or you want to choose each network component independently.

Consolidated Home Gateway

Internet, AC1900 WiFi, and Xfinity Voice are handled in one unit. Consolidation reduces the number of devices connected to the coaxial outlet and can simplify installation for compatible households.

Telephone Continuity During Outages

The optional battery backup is designed to support calls when household power fails. It adds resilience for users who rely on traditional voice service, although the battery accessory is not included.

Four Gigabit Ethernet ports provide wired connections for computers, streaming equipment, consoles, and other devices. The dual-band router can support up to 1,750 Mbps of theoretical combined wireless performance, although actual results vary with distance, congestion, interference, and client capabilities. The modem also has 24 downstream and eight upstream channels for plans up to 600 Mbps.

This is a renewed product, so physical and cosmetic condition may vary. It is also approved for Comcast Affinity rather than the full range of Xfinity services, and it is not compatible with faster Gigabit Xfinity internet packages. It also does not support Xfinity home security or home control without the required Xfinity home router.

The SVG2482AC is most appropriate for a qualifying Comcast Affinity customer with an internet plan up to 600 Mbps, traditional telephone service, and a desire for integrated WiFi. Check the current service terms and compatibility before purchasing. For broader Xfinity Internet and Voice compatibility, the T25, CM2050V, CM1150V, and C7100V are clearer choices.

Three-in-One Renewed Design

The SVG2482AC packages internet, dual-band WiFi, and telephony into a single renewed unit. It can simplify setups for eligible Comcast Affinity customers while reducing the number of separate home-network devices.

Connection Options for Many Devices

Four Gigabit Ethernet ports support direct connections for high-traffic equipment. The simultaneous 2.4 GHz and 5 GHz bands offer flexibility for nearby and distant wireless clients, subject to real-world interference and coverage.
