Call tracking
How does call tracking work for a law firm, and is recording calls legal?
Tracking numbers, numbers that swap per visitor, keeping your listings consistent, what recording laws say in four countries, and tying each call to a signed case.

The short answer
If you read one part of this page, read this.
Call tracking gives each marketing source its own phone number that forwards to your line, so you can see which channel made the phone ring. On your website, the number can change per visitor, which ties a call to the exact ad or page that produced it.
Recording those calls is legal in many places, but not everywhere on the same terms. US federal law lets one party to the call consent, but states can be stricter: California, Florida, Illinois, Washington, Maryland and Massachusetts require everyone's consent. Canada, the UK and Australia each expect callers to know. A recorded announcement at the start of every call covers the common ground.
Below: how tracking numbers work, where never to use them, what the laws we read actually say, and how to get from a ringing phone to a signed case in your CRM. We work with law firms across the US and Canada, and also in Australia and the UK.
How it works
A tracking number is a forwarding number with a label on it.
The caller dials a number tied to one source, the call rings through to your normal line, and the system logs where it came from, when, how long it lasted and, if you turn it on, a recording.
- Static numbers: one per source
One number for a radio spot, another for a bus bench, another for a printed directory ad. Anyone who dials that number came from that source, or kept it from that source. Simple, and fine for anything offline.
- Dynamic numbers: one per website visitor
This is dynamic number insertion. A small script on your site shows each visitor a number from a pool and remembers which visit, page, campaign and ad click it was shown with. When that number rings, the call inherits the visit's source.
- What the caller notices
Nothing. Caller ID passes through, so intake sees the real caller's number, and the call sounds like any other. Many systems can play a whisper to the person answering, such as "Google Ads call", before connecting.
Here's a check we run on every landing page we launch: open the live page in a normal browser and look at the phone number. If it's different from the firm's real number, the swap is working and calls are being tracked. If it shows the real number, every call from that page is anonymous.
Which numbers go where
Tracking numbers belong in ads and on your site. Your real number belongs on your listings.
Each kind of number has a home. Mixing them up is how firms end up with three phone numbers on Google and calls nobody can attribute.
| Number | Where it shows | Who owns it | Never put it on |
|---|---|---|---|
| Your real main line | Business Profile, Bing Places, directories, letterhead | The firm | Nothing to avoid; it's the anchor |
| Dynamic pool numbers | Your website and ad landing pages, swapped per visitor | Your call tracking system | Listings or print, where the swap can't happen |
| Static tracking numbers | One offline source each: radio, print, a sponsorship | Your call tracking system | More than one source |
| Google forwarding numbers | Inside Google Ads only | Google, which can reassign them | Anything outside Google Ads |
| Local Services Ads numbers | Your LSA listing, set by Google | Anywhere else |
Google's own forwarding numbers, call length settings and imports have their own guide: tracking calls from Google Ads. Local Services Ads leads, including calls, already sit in the account's Leads view with Google's numbers, so they don't need a tracking number of yours as well.
Your Business Profile number
Keep one real, local number on your Business Profile and every listing.
Google's Business Profile guidelines ask for a number that connects to your location and is under the business's direct control. A swapping number can't sit on a listing anyway, so the listing is where your real number lives.
- "Provide a phone number that connects to your individual business location."
- "Use a local phone number instead of a central call center helpline number whenever possible."
- "Do not provide phone numbers or URLs that redirect or 'refer' users to landing pages or phone numbers other than those of the actual business."
- "The phone number must be under the direct control of the business."
AI tools and maps compare your details across sources. A tracking number on Bing Places, another on Yelp and a third on the website reads as three different firms, or one firm with messy records. When we set up listings, the real number goes everywhere and stays there.
If you inherited a profile with a tracking number on it, change it back to the real line and update the directories at the same time. Our guide to how ChatGPT picks law firms explains why matching details matter for AI answers too.
Is recording legal?
Some places need one party's consent, some need everyone's, and an announcement covers both.
When your own system records, the firm is the party doing the recording. In one-party places the firm's own consent can be enough; in all-party places, the caller has to agree too. These are the laws we read, in their own words where possible.
| Where | What the law says | What it means for intake calls |
|---|---|---|
| United States, federal | 18 U.S.C. 2511(2)(d): lawful where the person is a party to the call or one party has given prior consent, unless the purpose is a criminal or tortious act | Federal law is one-party. State law can be stricter |
| California | Penal Code 632: recording a "confidential communication" without "the consent of all parties" is an offense, with fines up to $2,500 per violation | A first call about someone's legal problem is the kind of call that can be confidential |
| Florida | Statutes 934.03(2)(d): interception is lawful "when all of the parties to the communication have given prior consent" | Everyone on the call needs to have agreed |
| Illinois | 720 ILCS 5/14-2(a)(2): recording a private conversation you're part of, in a surreptitious manner, needs "the consent of all other parties" | Recording openly, with notice, is the point |
| Washington | RCW 9.73.030: consent of all participants; an announcement to everyone that the call will be recorded counts as consent, if the announcement is itself recorded | A recorded announcement is the statute's own method |
| Maryland | Courts and Judicial Proceedings 10-402(c)(3): lawful where the person is a party and "all of the parties" have given prior consent | Everyone on the call needs to have agreed |
| Massachusetts | G.L. c. 272, s. 99: "interception" means to secretly hear or record without "prior authority by all parties" | Open, announced recording is the safe route |
| Canada | Criminal Code s. 184: intercepting a private communication is an offense, but not with the express or implied consent of the person making it or the person it's meant for. The Privacy Commissioner says businesses under PIPEDA must tell the caller, state the purpose and get consent | Announce it, say why, and offer another way to talk if they decline |
| United Kingdom | The ICO's guidance on monitoring calls: "You must tell these people that you are recording the call and why." A recorded message is good practice | Announce it, and have your privacy information ready |
| Australia | The federal Telecommunications (Interception and Access) Act 1979 makes it an offense to intercept a call without the knowledge of the person making it, as the Australian Law Reform Commission summarizes sections 6 and 7. States have their own surveillance laws | Tell the caller, and check your state's law with your law society |
Callers don't stay inside your state lines. Someone can call a Florida firm from a California hotel. We don't try to work out which state's law governs a call that crosses a border; a recorded announcement at the start of every call answers the question for all of them.
Google adds its own layer. When call reporting is on for Google Ads in the US and Canada, Google now records calls by default and plays callers a short message saying so. This is a plain summary for marketing planning, not legal advice. Check the current rule with your bar or law society.
Doing it properly
Announce it, say why, and treat recordings like the rest of the file.
The practical version of all those laws is short. Tell every caller before the conversation starts, keep the purpose narrow, and limit who can listen later.
Play a recorded announcement on every tracked line
One plain sentence before the call connects: "This call may be recorded for quality and training." Make sure it plays on after-hours routing and on the answering service line too.
State the real purpose
Canada's Privacy Commissioner says not to call it quality assurance if the recording will be used for marketing or profiling. Say what you'll actually use it for.
Give people another way to talk
Some callers won't want a recording. Intake should be able to offer a call back on an unrecorded line or an in-person meeting without fuss.
Limit who can hear recordings
A first call can include an arrest, a diagnosis or a custody fight. Restrict playback to the people who need it, and set how long recordings are kept.
Tell your staff and your answering service
The ICO says to make sure workers know recordings may be released on request. Google's call terms also say you've told your own agents and employees.
Reviewing calls
Listen for four things: was it answered, was it relevant, what was the next step, and where did it come from.
Recordings and transcripts are only worth keeping if someone uses them. A weekly pass over the week's calls catches more than any dashboard.
- Answered or missed
Our call review sheet has a "Picked up" box on every call: ticked means a person answered, unticked means missed. The pattern of misses (lunch, court days, after 5pm) tells you where cover is needed, which our answering service guide covers.
- Relevant to the firm's services or not
Is this a matter the firm handles, in the area it serves? That's the only positive label we use on a call: "Relevant to services". A recording can't tell you whether the person later signed, so we never mark a call as converted from listening to it. Intake marks signed cases in the CRM.
- Did the caller get a next step
A booked consultation, a call back time, a document request. Calls that end with "we'll be in touch" are where cases leak.
- Noise to filter out
Existing clients, vendors selling to the firm, job seekers, wrong numbers. They're real calls, but they aren't leads, and counting them makes every channel look better than it is.
In our client work, each call is recorded and transcribed by the CRM and matched to its lead by phone number. When a call can't be matched, it lands on a separate tab that we check by hand, so no transcript goes missing. That matters on days like the one an employment and injury firm had when it took 10 qualified calls in one day, 5 signed within 24 hours.
From call to signed case
A tracked call is only useful once the CRM knows whether it signed.
Call tracking tells you which source made the phone ring. The CRM tells you which rings became clients. You need both to compare channels.
Every call creates or updates a contact
The call tracking system pushes the caller's number, the source and the recording into the CRM. A repeat caller updates the same contact rather than becoming a second lead.
Intake sets the stage the same day
Contacted, consult booked, consult held, signed, not a fit. Our intake metrics guide explains each stage.
Signed cases keep their original source
When a caller from a Google ad signs six weeks later after a referral partner vouched for you, the record should show both. Our guide to marketing attribution covers first and last touch.
Compare channels monthly
Calls, real leads and signed cases by source, next to ad spend. That's your cost per signed case.
Family firms get calls from everywhere: profile, ads, referrals and now AI answers. One family law firm that shows up in ChatGPT added 50 to 100 calls a month over three months. When a new source starts producing calls like that, tracking is how you see it next to the others. More on that practice on our family law marketing page.
Common mistakes
Where firms go wrong.
The call tracking and recording mistakes we see when firms come to us.
A tracking number on the Business Profile
It breaks the match between your profile, your site and your directories, and Google's guidelines ask for a number under the firm's direct control.
Recording without an announcement
In all-party states, and under Canada's privacy rules, a silent recording is the problem. One recorded sentence before the call connects fixes it.
Forgetting the after-hours path
The announcement plays on the main line but not on the overflow to the answering service, which is where the late-night calls go.
Counting every ring as a lead
Existing clients and vendors call tracked numbers too. Mark them, or every channel looks stronger than it is.
Tracking calls but never marking outcomes
Without signed cases in the CRM, call tracking can only tell you which channel makes noise.
Real results
What this looked like for real firms.
Three firms where the phone was the story: 10 qualified calls in one day, 50 to 100 extra calls a month from ChatGPT, and a bankruptcy firm whose phones wouldn't stop ringing.

FAQ
Questions lawyers ask us.
Straight answers to the questions that come up most.
Is call tracking legal for a law firm?
Tracking where a call came from is ordinary marketing measurement. Recording the call is where consent laws apply. Federal law allows one-party consent, but states including California, Florida, Illinois, Washington, Maryland and Massachusetts require all parties to agree, and Canada, the UK and Australia expect the caller to know. Announce recording on every call.
Do I have to tell callers the call is recorded?
In all-party states, yes, and in Canada the Privacy Commissioner says businesses under PIPEDA must tell the caller, state the purpose and get consent. The UK's ICO says to tell callers and why. Even where one-party consent applies, an announcement costs nothing and removes the question.
Will a tracking number hurt our Google ranking?
On your website, a number that swaps for visitors doesn't change what's on your Business Profile. The risk is putting tracking numbers on listings, where Google, Bing and directories compare your details. Keep your real number there.
Can existing clients end up on tracking numbers?
Yes, if they found you through the website. That's why we mark existing clients separately in the call review instead of counting them as leads. Some firms give clients a direct line in their engagement letter to keep them off marketing numbers.
Do we need call tracking for Local Services Ads?
Not for the leads themselves. Google already shows each LSA call in the Leads view, and charges per lead. Tracking still helps on the website and other ads, so every channel ends up in the same CRM. Our Local Services Ads service covers how we review those leads.
Does call recording work the same in Canada?
The Criminal Code allows recording with the consent of either the caller or the person called, and federal privacy law adds the duty to tell the caller and say why. The Commissioner's page applies to businesses under PIPEDA and offers its guidelines to everyone else as good practice, so check which privacy law covers your firm. Google's own call recording covers calls where both numbers are in the US or Canada.
Can you set up call tracking for us?
Yes. Our systems work covers tracking numbers, recordings, the CRM pipeline and reporting from call to signed case, and the firm owns all of it. Schedule a consultation and we'll look at how calls reach you today.
