Law firm missed calls: how many do you really miss?

To find out how many calls your law firm misses, export three months of call records from your phone provider, remove internal and duplicate calls, and count the external calls that were never answered and never returned. Split the result by hour and by line. Most firms find the number is higher than anyone guessed, and clustered in predictable moments.

We have written about what a missed enquiry costs in what missed enquiries actually cost a UK law firm, and about the US research that put the problem on the map in only 40% of law firms answer the phone. That US study, the Clio Legal Trends Report 2024, found 40 per cent of 500 firms answered a prospective client's call. Both posts end with the same instruction: measure your own firm, because no UK equivalent has been published. This is the method for doing that properly, including the traps that make a firm's phone data look better or worse than it is.

Why don't law firms know how many calls they miss?

Because a missed call leaves almost no trace in the places partners look. A lost pitch is discussed at a partners' meeting. A caller who rang at 12:55, heard the phone ring out and rang the next firm on their list appears nowhere except a line in a call log nobody opens.

There is a second reason, which is that everybody's impression is formed by the calls they took. The receptionist remembers a busy morning in which she answered everything she could. The fee-earner remembers returning three messages. Nobody experiences the calls that were never answered, because by definition nobody was there.

Where do you get your firm's call data?

Almost every business phone system can produce a call detail record export: one row per call, with the time, the number that called, the number or extension it reached, how long it rang, whether it was answered and how long it lasted. On a hosted or cloud phone system it is usually a report in the admin portal. On an older on-site system, your maintainer can usually produce it. If you are on mobiles, the network's business portal may have it.

Ask for three months, as a spreadsheet, including unanswered and abandoned calls. Some default reports show only answered calls, which is exactly the wrong way round for this exercise. If the provider asks what you need it for, say you are measuring answer rates by hour; they will know what to give you.

Which calls count as missed?

This is where most attempts go wrong. The raw number of unanswered rows is not your missed-call rate, and treating it as one will either frighten or reassure the partners for the wrong reasons. Use five definitions and keep them separate.

• Unanswered: an external call that rang and was not picked up by anyone, including calls that went to voicemail.
• Abandoned: the caller hung up while waiting, in a queue or while it rang. On many systems these are recorded separately from unanswered calls. Count them as missed.
• Voicemail left: an unanswered call where the caller left a message. This is the only kind of missed call the firm is told about.
• Recovered: a missed call where somebody at the firm rang the number back, or the caller got through on a later attempt, within a time you define (we suggest the same working day).
• Lost: a missed call that was never recovered. This is the number that matters.

Keep unanswered and lost apart. A firm that misses a lot of calls but returns nearly all of them the same day has a coverage problem that is costing it goodwill. A firm that misses fewer but returns hardly any has a follow-up problem that is costing it instructions.

What are the traps in the data?

• Hunt groups count one call several times. If a call rings reception, then a secretary, then a second secretary, some systems log three unanswered legs and one answered one. Deduplicate on the caller's number and the start time before counting.
• Internal calls inflate the total. Transfers between extensions and staff ringing each other are not enquiries. Filter to external callers only.
• Menu drop-offs are hidden. If you use a "press 1 for conveyancing" menu, callers who hang up during the menu may not appear as unanswered at all. Ask the provider whether the export includes calls that ended in the menu.
• Withheld numbers cannot be returned. Count them, but put them in their own line, because nobody could have rung them back.
• Existing clients and suppliers are mixed in. A missed call from the other side's solicitor is not a lost enquiry. Match numbers against your client and contact lists where you can, and at least mark the obvious ones.
• Direct dials are forgotten. Calls to a fee-earner's direct line, or a mobile, are often outside the main report. They are where existing clients and returning clients ring. Include them if the system can.

How do you calculate your missed-call rate?

Once the data is clean, four numbers do most of the work:

• Answer rate: answered external calls divided by all external calls, after deduplication.
• Voicemail rate: voicemails left divided by missed calls. This tells you how many missed callers the firm even knows about.
• Same-day recovery rate: missed calls rung back or reconnected the same working day, divided by missed calls.
• Lost-call count: missed calls never recovered, per month. Put this one on the partners' agenda.

Then split each by hour of the day and day of the week, and by line if you have more than one. A simple grid of hours down the side and weekdays across the top, shaded by missed calls, is the most persuasive single page you can put in front of a partner. It usually shows the pattern without any commentary: lunchtime, the first half hour of the morning, late afternoon, and the evening.

A worked example

The figures here are invented to show the method. They are not a benchmark and describe no real firm.

A four-partner firm exports three months of calls. The raw export has 5,100 rows. Removing internal calls leaves 3,400. Deduplicating hunt-group legs leaves 2,600 genuine external calls. Of those, 2,080 were answered and 520 were missed: an answer rate of 80 per cent, which the partners find reassuring.

Then the detail. Of the 520 missed calls, 150 left a voicemail. All 150 were rung back, most the same day. Of the 370 that left no message, staff noticed and returned 60 from the missed-calls list. That leaves 310 missed calls, over three months, that nobody ever returned: roughly 100 a month.

Matching the numbers against the client list shows about a third were existing clients or known contacts, most of whom rang again. That still leaves something like 65 calls a month from numbers the firm had never seen before, which were not answered and never returned. Around half fell between 12:30 and 14:00 or after 17:00.

The firm's 80 per cent answer rate was accurate. It was also not the number that mattered. The number that mattered was 65 unknown callers a month, and the firm had never seen it.

What do missed calls cost a law firm?

Once you have the lost-call count, the cost is straightforward arithmetic, and we have set it out in detail in what missed enquiries actually cost a UK law firm. In outline: take the lost calls from unknown numbers, estimate what share were genuine enquiries for work you do, multiply by your usual conversion rate and your average fee per matter. Treat the result as a ceiling, not a forecast. If you do not know your conversion rate, how to measure your enquiry-to-instruction conversion rate sets out how to find it.

Why do law firms miss so many calls?

Look at the hour-by-day grid and the reasons usually name themselves. They are rarely about effort.

• One front desk, several lines. A second call while the first is being handled rings out or queues.
• Lunch and breaks. The desk is covered by whoever is nearest, or by nobody.
• Court and meetings. A fee-earner's direct line goes unanswered for a whole day, and their clients know the number.
• The end of the day. Many people ring a solicitor when they finish their own work, which is when the office closes.
• Voicemail as the only fallback. Many callers with a pressing problem hang up rather than leave a message, so voicemail tends to filter out the very callers the firm most wants to reach. We look at that in what your law firm voicemail says to a new client.

How do you reduce missed calls at a law firm?

Fix them in order of cost, cheapest first.

• Return every missed call from an unknown number the same day. Make someone responsible for the missed-calls list at fixed times, say 12:00, 15:00 and 17:15, with a back-up. This costs nothing and attacks the lost-call count directly.
• Cover the specific windows the grid shows. Stagger lunches. Make sure a second person can pick up when the first line is busy. Move a direct dial to overflow to reception when a fee-earner is in court.
• Change what happens when nobody can answer. A voicemail greeting that promises a call back and names when helps. Something that actually answers, whether an answering service or AI call-handling software, helps more, provided it captures enough detail to act on and tells the caller honestly what it is.
• Measure again in a month. Same export, same definitions. The lost-call count should fall first.

If you do decide to add cover, the options and their trade-offs are laid out in who answers your law firm's phone after five, and the cost side of an outsourced service is in how much an answering service costs.

Where WasilX fits

Cam, our AI Engagement Coordinator, takes calls on the firm's line at any hour, says it is AI, asks the firm's own qualifying questions, books the call back and sends the firm a summary. On the grid above, that turns the shaded squares into captured enquiries with a next step. It does not replace the same-day ring-back discipline for everything else, and a firm with a low lost-call count may not need it at all.

Frequently asked questions

How do I find out how many calls my law firm misses? Ask your phone provider for a call detail export covering three months, including unanswered and abandoned calls. Remove internal calls and duplicate hunt-group legs, then count external calls that were never answered and never rung back.

What is a good answer rate for a law firm? There is no published UK benchmark we would rely on. The more useful measure is the number of missed calls from unknown numbers that were never returned. If that is close to zero, your answer rate matters much less.

Should missed calls from existing clients be counted? Count them, but separately. They are rarely lost instructions, because clients usually ring again, but they are a service problem and a common source of complaints about communication.

Does voicemail solve the missed-call problem? Only partly. It captures the callers willing to leave a message, and gives no information about those who hang up, who in many firms outnumber those who do. See what your law firm voicemail says to a new client.

How often should we check the missed-calls list? At fixed times during the day, with a named person and a named back-up. Three checks, late morning, mid-afternoon and just before close, catch most calls while the caller is still deciding who to instruct.
