Built for

Law firms, CPA firms, and consulting practices — boutique, multi-partner, and hybrid.

Five shapes of US professional-services practice live on Leyline today — from a single-partner boutique to a multi-state firm with a hundred seats. Same engineer, same per-user license, same nationwide posture across all of them.

  • Boutique & mid-size law firms.
    Time-of-day routing, secure client intake, and a softphone the partners can take to depositions and back — without dragging a desktop handset off-network.
  • Multi-partner / multi-state firms.
    One directory across the home office and every satellite, with shared greetings, attended transfers between partners, and one per-user license that travels with the attorney.
  • CPA firms & seasonal tax practices.
    Auto-attendant menus that survive a January ring storm, encrypted voicemails for client-confidential intake, and seasonal seats that scale up and back down on one invoice.
  • Management & IT consulting.
    A client-facing number that follows the consultant onto a client campus and back, with HD video for kickoffs and an encrypted file room for the engagement deliverables.
  • Hybrid & fully remote practices.
    A nationwide US engineer on the rollout, pre-provisioned handsets for the few on-site, and a softphone for everyone else — same per-user seat, same shared directory.

Every firm on Elevate gets the same per-user license, the same nationwide engineer, and the same shared directory across every office.

What you actually get

Three things every multi-site firm gets on day one.

A professional-services cutover is not the same as a generic office cutover. The partners' numbers are the clients' lifeline, the satellite is two states over, and the intake line has to behave itself after hours.

What you get

Multi-site routing on one directory.

HQ, every satellite office, every home office — a single shared directory, with per-partner DID numbers and a roll-over plan that does not depend on the box in your closet.

How it shows up

One license per user, not per site — adding a fourth office is a config change, not a hardware refresh.

Built in, not bolted on.
What you get

Reliable remote setup for partners and consultants.

Softphone on every laptop, pre-provisioned handsets for the offices, and a number that follows the partner to depositions, client campuses, and back — without dragging a desk phone off-network.

How it shows up

A failed handset becomes a phone on a laptop overnight — the seat keeps working while the hardware is swapped.

Built in, not bolted on.
What you get

Professional call handling for client-confidential intake.

Auto-attendant, shared greetings, time-of-day routing, and encrypted voicemail — so a client call after hours lands on the right partner, not on a generic on-call line.

How it shows up

Configured once at cutover, edited in the same admin console your IT partner already uses.

Built in, not bolted on.

Not features on a slide. The posture every Leyline cutover is run on.

What you get

One per-user license, five firm-grade tools — plus a human-led migration.

VoIP, client-facing video, firm-wide chat, encrypted file rooms, and a white-glove migration under one Elevate seat. Pick what your firm needs today; add the rest when the matter demands it — the license line never multiplies.

01 — Voice

Hosted VoIP that holds up to client intake.

TLS + SRTP encrypted voice with auto-failover, so a partner on a deposition call does not have to think about the uplink — and a missed client call is a recoverable event, not a reputational one.

  • TLS + SRTP
  • Auto-failover
  • Per-user licensing

02 — Client-facing video

Video meetings for client calls and depositions.

HD multi-party video with screen-share and recording — so a remote witness prep or a tax-planning session with a client has the same polish as an in-room meeting, and the recording lands in the right shared drive.

03 — Firm-wide chat

Persistent team chat, channeled the way you bill.

Channels, DMs, presence, and document drop-in — on the same per-user seat as your phone line. A matter channel, a client channel, and an internal channel each stay where the rest of the work lives.

04 — Encrypted file rooms

Encrypted file rooms for client documents.

Encrypted-at-rest file sync with secure share links, granular permissions, and configurable retention — so engagement letters, returns, or contracts live next to the calls and messages about them.

05 — Migration

Engineer-led cutover, with a nationwide site survey.

A Leyline engineer runs a site survey of every office and remote partner, ports your numbers on a planned window, and walks an admin on your team through the console before handoff — not a courier drop-ship.

  • Nationwide site survey
  • Engineer-led cutover
  • Admin training

Why Leyline vs legacy PBX

What calling cloud-managed voice actually buys you over the box in your closet.

The PBX on the wall was a reasonable purchase — fifteen years ago. Today, a hosted per-user seat rolls out faster, scales with the firm, and carries the engineer who answers on day one.

  • Leyline — cloud-managed.

    Hosted, per-user license, nationwide US engineer. Adds a site, adds a partner — no hardware refresh, no truck roll, no second invoice per office.

  • Legacy PBX — box in the closet.

    Capital expense up front, per-site licensing, regional vendor coverage. Adding a fourth office means a fourth hardware conversation and a new maintenance contract.

  • Support — one engineer, not a queue.

    The Leyline engineer who ran your site survey is the one who answers when something breaks. The PBX vendor routes you through tier-one reading a script.

If your managing partner asks “what does a cloud upgrade actually buy us?”, the answer is the same as it was the day the proposal went out: a hosted seat, one engineer, and a single invoice that tracks headcount — not wall-mounted hardware.

Migration walkthrough

From the first call to fully cut over, with a nationwide site survey up front.

A firm cutover touches every partner, every satellite, and every after-hours intake line. The engineer who runs the site survey is the one who runs the cutover.

  1. 01

    A nationwide site survey.

    A Leyline engineer inventories every office and every remote partner, walks the director of operations through the current PBX, and writes a cutover plan with the per-user number on it.

  2. 02

    Pilot one office.

    Pick your smallest site. We ship pre-provisioned handsets, port the main number, and walk an admin on your team through the console — including after-hours routing and an intake menu.

  3. 03

    Roll out the remaining sites.

    Once the pilot has been live for two weeks, you set the pace. Most multi-site firms are fully cut over in under sixty days — including number ports, partner DIDs, and the seasonal seats.

  4. 04

    Stay on the engineer’s speed-dial.

    A real Leyline engineer answers when something breaks — the same one who staged your system, not a tier-one script reading from a queue.
