Phone Systems for Law Firms

Every call on the record, every callback answered, and intake that works after the office closes.

For a law firm, the phone is where matters begin and where billable details live. A missed intake call is a client another firm signed. An undocumented phone conversation is a dispute waiting for a memory contest. And a callback from an unrecognized number is a callback that rings out, because clients screen harder than anyone.

Cannon VoIP gives firms searchable records of every call, a direct line and forwarding rules for every attorney, branded caller ID so your firm's name appears on the client's screen, and after-hours intake that captures the 9 PM caller instead of losing them. Flat $34 per extension, no contracts, transcription included.

The three calls that cost firms money

The first is the intake call that rings while everyone is in deposition: the caller with a real matter and a short list of firms leaves no voicemail and dials the next name. The second is the callback that gets screened: "Unknown Number" from a cell phone loses to the client's spam filter, and the matter slips another day. The third is the call nobody wrote down: six months later, what was actually said becomes a matter of recollection.

None of these are lawyering problems. They are phone problems, and they are the exact three things a firm's phone system should be engineered around.

What we set up for law firms

Transcribed, searchable calls
Calls can be recorded per extension and are transcribed automatically, so what was said, and when, is searchable when a matter needs it. Voicemails arrive in email with transcripts attached.
A direct line for every attorney
Each attorney gets a direct number with a personal forwarding matrix: office hours ring the desk, court days ring the cell, and everything else lands in transcribed voicemail that reads like email.
Callbacks that get answered
Branded Calling puts the firm's verified name and logo on the client's screen instead of a bare number. Fewer ignored callbacks and fewer voicemail loops on time-sensitive matters.
After-hours intake that converts
The AI receptionist answers around the clock, takes structured intake messages, books consultations against real calendar availability, and sends the caller an SMS follow-up so the firm is the one that responded first.
Calls inside Microsoft Teams
Attorneys who live in Teams can make and take firm calls there through Direct Routing, with no separate Microsoft calling plan. CRM users get automatic call logging with AI summaries in Salesforce, HubSpot, Zoho, and more.
Paralegal and staff routing
Ring groups put a matter's team on one number, whisper and barge tools let a partner coach an associate through a difficult call live, and sticky routing sends a returning client to the person who already knows the file.

Why firms switch to Cannon VoIP

Pricing stays flat at $34 per extension per month with no contracts, which matters to firms that add associates in bursts and shed office space between leases. Texting from the firm's number is included, so "running 10 minutes late" reaches a client from a number they recognize rather than a paralegal's cell.

The firm's published numbers never change: porting is $15 per line, most numbers move the next business day, and lines are down about two minutes during the switch. Letterhead, bar listings, and twenty years of business cards stay accurate.

Recording deserves a straight answer: consent rules differ by state, including one-party and two-party jurisdictions, and recording here is configured per extension so the firm controls exactly what is captured. We will help you configure it to match your jurisdiction; that is configuration help, not legal advice, and you know that distinction better than we do.

What a typical setup looks like

A five-attorney firm typically runs eight to ten extensions: each attorney, reception, a paralegal ring group, and a conference room, at $34 each. Reception answers with day and after-hours menus; unanswered intake rolls to the AI receptionist at a flat $65 rather than to voicemail. Attorneys carry one extension across desk phone, laptop, and mobile app, so a courthouse hallway callback still shows the firm's number.

Older desk phones mostly carry over; anything new ships preconfigured overnight. The whole cutover is typically one port date and one afternoon.

Common questions from law firms

Can we record some lines and not others?
Yes, recording is per extension. Firms commonly record intake and main lines while leaving attorney direct lines unrecorded, or the reverse. Transcription follows the same control, and retention is documented so your records policy has something to point at.
Do attorneys have to carry two phones?
No. The mobile app puts the firm extension on a personal phone, calls out show the firm number, and after-hours rules decide when it rings at all. One device, two identities, and the personal number stays private.
We already use Teams for everything. Does this replace it or fight it?
Neither, it plugs in. Direct Routing delivers real phone calls inside Teams with no Microsoft calling plan, so the firm keeps one interface and gains a real phone system behind it.

Solo practitioners: this scales down to two extensions, month to month, with the AI receptionist as your after-hours intake desk. The system that serves a 40-attorney firm is the same one, just bigger.
