How law firms actually use phones

A law firm phone system has different demands from a typical small office. Most calls have at least one of three characteristics: they're confidential, they're time-sensitive, or they're from someone whose case depends on reaching their lawyer. None of those tolerate a generic phone setup that drops calls to voicemail or routes a sensitive client matter to the wrong attorney.

NYC firms span every size from solo practitioners to mid-sized boutiques to multi-partner offices. The right phone system depends on the practice, but the constants across all of them are:

The phone system needs to match how attorneys actually work. Most generic VoIP setups don't.

What features matter most for law firms

Mobile softphone for attorneys

The single most-used feature for litigators and any attorney with court days. The mobile app (iOS and Android) lets attorneys answer their direct firm line from anywhere, with the firm's caller ID showing on outbound calls. Personal cell numbers stay private. A litigator in court for the morning can step out, return a client call from the hallway, and the client never knows the attorney isn't at the office.

The same app works from depositions, client sites, courthouses, the train ride home, or anywhere else. The desk phone and the mobile app share the same extension; calls to the attorney's direct line ring both.

Multi-level routing for partners and associates

A typical NYC firm phone tree starts with reception or an auto-attendant ("for the office, press 1; for [Attorney Name], press their extension; for a partner directory, press 2..."), then routes based on what the caller needs. Different attorneys have different preferences:

Per-attorney routing rules are configured during install and adjustable any time. The system can flex around vacation, court schedules, and trial weeks.

Conference bridges

Three-way calls and small conference calls are routine for law practice (client + attorney + opposing counsel, client + attorney + expert witness, partner meetings with remote attorneys). The conference bridge is part of the standard PBX; no separate Zoom-style service required for audio-only conferences. Joining is just dialing a conference extension or having the system bridge participants together.

Private voicemail boxes

Each attorney's voicemail is private to their extension. Only the attorney (and any designated admin) can access it. This matters because voicemails from clients are typically privileged communications. Privacy posture is built into the configuration during install.

Reliable failover

Cloud phone systems require Internet to operate. If your office Internet goes down during a critical client call, the system goes down with it. For law firms, we recommend the 5G LTE failover add-on. When fiber drops, the system automatically routes through cellular. Calls keep working. The attorney's mobile app continues working on cellular data regardless of office Internet status.

For a litigator, missing a call from opposing counsel about an emergency motion isn't an inconvenience. It can affect a case. The phone system isn't just office equipment; it's part of the attorney's professional infrastructure. It needs to work like infrastructure works: predictably, every time.

The call recording question

Call recording is a feature most law firms ask about during the buying conversation. The answer is more nuanced than a typical business.

The legal status in New York

New York is a one-party consent state for call recording. Recording is legal as long as one party to the conversation consents. Your attorney is a party, so recording attorney-side calls is legally permissible under NY wiretap law.

The professional responsibility layer

Legal status is only one piece. The Rules of Professional Conduct add considerations. Some questions firms should think through with their ethics counsel:

This is not legal advice. Consult your firm's ethics counsel before configuring call recording for client communications. We configure the recording feature however your firm directs us.

What's included on the Business plan

500 minutes of call recording per month is included on the Business plan. Additional capacity is available as an add-on for firms with heavier needs. Some firms turn off recording entirely for client matters and only use it for internal training or specific cases; others record all calls and manage the storage/retention separately. The system supports either approach.

After-hours coverage

Different law practices have different after-hours needs:

The phone system handles all of these through time-based routing. Business hours follow the standard rules. After hours route differently based on your practice:

Example, 6-attorney NYC personal injury firm

Main number rings during business hours to a hunt group that includes the receptionist plus all attorneys' mobile apps. The receptionist picks up first if available; otherwise it rolls to whichever attorney is free.

After hours, the same number routes directly to the on-call attorney's mobile (a rotating weekly schedule). Voicemail catches anything they don't pick up, with the message delivered to their email and to the office admin for follow-up the next morning.

If the attorney's phone is unreachable (no cellular signal in a courthouse basement, for example), the call rolls to a backup attorney's mobile, then to the voicemail box. Most after-hours calls reach an actual attorney within two minutes.

Bilingual reception for NYC firms

NYC client populations are linguistically diverse. Firms serving immigrant communities, family law clients, criminal defense clients, and certain practice areas regularly handle calls from Spanish, Mandarin, Cantonese, Russian, Yiddish, Bengali, Polish, Haitian Creole, and Korean speakers.

The phone system supports multi-language IVR as a standard feature. A caller hears a language-selection prompt, picks their language, and the entire menu plays in that language. We cover the setup in detail in our multi-language IVR walkthrough; the same setup works for law firms.

What to ask your phone-system provider as a law firm

Questions that separate real providers from generic ones when you're shopping:

  1. Can each attorney have a different routing rule (e.g., senior partner gets screened by admin; junior associate gets calls direct)?
  2. How does the mobile app handle the firm's caller ID? Can it be configured per attorney?
  3. What's the call-recording capacity, and how can it be turned off for specific extensions or call types?
  4. How are recordings stored, and what's the retention policy?
  5. Can voicemails be routed to specific email addresses for follow-up tracking?
  6. How is the system configured to maintain attorney-client privilege expectations?
  7. What's the failover plan if office Internet goes down?
  8. How does the system handle multi-party conference calls?
  9. Is the support team local to NYC? Can someone come on-site for adjustments after install?

Frequently asked questions

What phone system features matter most for NYC law firms?

Mobile softphone for attorneys away from desks, multi-level routing per attorney, conference bridges, private voicemail per extension, careful call recording configuration, after-hours coverage matched to practice area, and reliable failover.

Is call recording on attorney calls legal in New York?

NY is a one-party consent state, so recording attorney-side calls is legally permissible. However, professional responsibility rules and attorney-client privilege add considerations around disclosure, storage, retention, and discovery. Consult your ethics counsel before configuring recording for client calls.

How do partners and associates share coverage?

Per-attorney routing rules. Hunt groups, direct extensions, mobile apps, and screening flows are configured during install and adjustable any time. Senior partners get screened by admin; junior associates get direct calls; practice groups can share a hunt group.

Can attorneys answer firm calls from outside the office?

Yes. The mobile app routes calls to attorneys' personal phones with the firm's caller ID showing on outbound calls. Personal cell numbers stay private. Essential for litigators in court and transactional attorneys traveling for closings.

What's the right phone system for a small NYC law firm?

Business plan at $29.99 per user per month for most 3 to 10 attorney firms. Includes desk phone, mobile app, full PBX, 500 minutes of call recording, unlimited US/Canada calling. Standard plan at $19.99 per line works for solo practitioners with minimal call volume.

How does confidentiality work on shared lines and voicemail?

Each attorney's voicemail is private to their extension. Direct extensions don't ring other phones unless configured. Conference rooms and admin lines are typically separate from attorney direct lines. Configuration during install ensures the privacy posture matches your firm.

What if the office Internet goes down during a client call?

Without failover, the system goes down with the Internet. We recommend 5G LTE failover for law firms as an add-on. The mobile app also continues working on attorneys' cellular data regardless of office Internet.
