Why NYC offices are leaving Optimum

Optimum (owned by Altice USA, formerly known as Cablevision in NYC) is one of the major cable providers serving the tri-state area. In NYC, Optimum has strong coverage in parts of the Bronx, Brooklyn, and Staten Island. Their Business Voice products, both the traditional cable phone service and the newer Hosted Voice cloud PBX, ship bundled with Optimum Internet.

The same structural patterns that drive offices away from other cable carriers also apply here:

  1. Bundle structure controls the pricing. Optimum's advertised rates assume you're taking Internet from them. Standalone phone pricing is less transparent and typically higher. The bundle creates dependency, changing your Internet provider later means renegotiating phone service too.
  2. Cable Internet dependency. Optimum Business Voice runs over the Optimum Internet connection. When the Internet has an outage at your address, the phones go down too. Phone reliability becomes a function of Internet reliability.
  3. National dispatch model. Optimum handles field service through a national dispatch system. Different techs may show up across repeat visits, and arrivals don't always hit scheduled times. Accountability is distributed across the dispatch system rather than tied to a person you can reach directly.
  4. Limited modern features on the lower tiers. Optimum Business Hosted Voice has competitive features at its higher tiers, but the lower-priced plans miss things like queue callback, hot desking, and full mobile/desktop softphone parity.
For NYC offices that want phone service independent of their Internet provider, the cable model has structural limits that aren't going to change.

Two paths if Optimum is your only good Internet option

Many NYC buildings, especially older commercial buildings in parts of Brooklyn, the Bronx, and Staten Island, have Optimum as the only fiber-coax option, with the alternative being limited DSL or no broadband at all. If that's your situation, you might think you're stuck with the Optimum bundle. You're not. There are two clean paths:

Path 1: Keep Optimum Internet, switch only the phone

LightningVoIP is a standalone phone service. Your Internet provider is your choice. Keep Optimum Internet (or any other Internet provider) and move the phone service to us. The two services are now independent:

Path 2: Add 5G LTE phone failover for outage resilience

If you're worried about Optimum Internet outages affecting your phones (a real concern for some NYC buildings), we can add 5G LTE failover as a phone backup. When the Internet goes down, the phones route over cellular until Internet comes back. The phone system stays operational independent of what's happening with your Internet provider.

This is a feature cable-carrier phone services typically can't offer because their phones ARE the Internet, there's no separate cellular path.

Switching from Optimum, what the migration actually looks like

Week 1, Discovery

We come on-site to review your existing Optimum setup. Inventory lines, extensions, call routing, voicemail boxes, any custom IVR programming. Confirm your Optimum service terms, many offices are on multi-year contracts, so we map out the early-termination math if relevant. Provide a fixed quote and a written migration plan.

Week 2, Parallel build

Provision the new cloud PBX with all your extensions and call flows matching your current Optimum setup. New IP desk phones programmed for your team. Your Optimum service keeps running normally, no caller-facing changes yet.

Week 3, Number porting and cutover

Number porting from Optimum takes 7 business days on the carrier side. We schedule cutover for a weekday morning. Your Optimum service stays active until your new line is verified working. Cutover window is typically under 15 minutes of perceptible activity.

Week 4, Training and tuning

On-site session with your team. Mobile app training, IVR tuning based on real call patterns. After this, you reach a real engineer directly for support, the same small local team every time.

When NOT to switch

Honest framing, we'll tell you straight if any of these apply:

Our typical fit: the NYC small office on Optimum Business Voice or Hosted Voice that wants standalone phone service, real local support, and modern features at predictable monthly pricing.

Frequently asked questions

What's the difference between Optimum Business Voice and Optimum Business Hosted Voice?

Business Voice is the traditional cable-delivered phone service. Business Hosted Voice is the newer cloud PBX product with more features. Both still bundle with Optimum Internet for advertised pricing.

Why are NYC offices leaving Optimum for other providers?

Three structural reasons: phone is bundled with Internet (no standalone discount), phone service depends on cable Internet (outages affect both), and support runs through national field dispatch with rotating techs.

Can I keep Optimum Internet but switch the phone?

Yes. LightningVoIP is standalone, your Internet provider is your choice. Keep Optimum Internet, move only the phone to us. The two services are now independent.

Does Optimum operate everywhere in NYC?

Optimum has strong coverage in parts of the Bronx, Brooklyn, and Staten Island. Manhattan and parts of Queens see more Verizon Fios and Spectrum. Your specific address determines availability.

Will I lose my phone number when switching from Optimum?

No. Number porting takes 7 business days, included in every plan. Optimum service stays active during porting. Cutover window typically under 15 minutes.

What if my building only has Optimum for Internet?

Keep Optimum Internet, switch only the phone to us. Optional: add 5G LTE failover so phones survive any Internet outage.

How does LightningVoIP compare to Optimum's tech dispatch?

Brooklyn-based, NYC-local techs only, no subcontractors. The person you talk to during install is the person who handles support. Same-day on-site service across all 5 boroughs.
