How to get 30 days of call history from your phone company

Log in to your phone company’s online account and look for call history, call logs or call detail records. Download the past 30 days as a spreadsheet file (CSV or Excel), where the company offers one. If you cannot find it, call the company and ask what it keeps for your line.

Where it sits and how far back it goes depend on the company and the kind of line. The list below follows each company’s own help page as we read it on September 25, 2026. Menus change. If a step does not match, search for the help page by its title in the sources.

Where each phone company keeps it

Source: AT&T, “Access your Business Phone call history”; Cox Business, “Viewing Call Detail Records in MyAccount”; T-Mobile, “Print phone records”; Verizon, “Verizon mobile bill statement FAQs”; Quo, “Export data”. Vendor help pages, checked September 25, 2026.

• AT&T Business Phone. Sign in to the AT&T phone portal and select Call History. It shows “either your last 100 calls or calls for the last 60 days.” You can sort it by missed, answered or outgoing calls and download it as XLS, CSV or PDF. You can see it only after your first phone bill posts.
• AT&T business cell phones. Go to Usage and pick the billing period. Under the phone, select View usage details, choose Talk and download it as CSV or Excel. If the download is greyed out, page to the end of the records first. It reaches back up to 16 billing cycles.
• Cox Business, now Spectrum Business. Cox sells business phone service in Gainesville, and its site now says “Cox Business is now Spectrum Business,” so your account may be under either name. In MyAccount, click Voice, expand Reports and click Call Detail Records. Enter the dates, retrieve the data and export it from Table view as CSV or PDF. Records go back as far as 120 days, but Cox says this works only for IP Centrex customers. On any other Cox voice plan, or if you are not sure which one you have, call and ask.
• Verizon Business Digital Voice. The User Portal’s Call History page lists missed, placed and received calls. Verizon’s page does not say how far back it goes or whether it downloads. Only the site administrator can set up users in the portal. If that is not you, ask them for a login.
• Verizon cell phones. On Unlimited plans, the PDF bill in My Verizon shows call details; paper bills do not. You can download up to 24 months of past bills. That is Verizon’s consumer help page, and a business account may differ.
• T-Mobile cell phones. On a postpaid account, log in at T-Mobile.com, go to Usage, choose Calls, select the line and download the usage records. It reaches back up to one year. Same caution as Verizon: this is T-Mobile’s general help page, not a business one.
• Quo, formerly OpenPhone. Only the workspace Owner can export. Open Settings, then General, and under Export your data pick call logs. The CSV arrives by email within 24 hours and covers everything since the workspace was created. The download link expires after 72 hours.

When the last 100 calls cover less than a month

AT&T’s page does not say which limit applies, 100 calls or 60 days, so plan for the shorter one. The list holds missed, answered and outgoing calls, so the calls you make use up the 100 too. Say a shop makes and takes 8 calls a workday. That is an example, not a benchmark.

100 calls ÷ 8 calls a workday = 12.5 workdays, about two and a half weeks.

If the 100-call limit applies, that shop never sees a full month on the list. Download it every two weeks and keep the files.

How long phone companies keep call records

What you can see online is up to each company. On the pages above, it runs from the last 100 calls to 24 months of bills, and on Quo, the whole history.

One federal rule sets a minimum, for billing. A phone company that offers or bills toll service must keep, for 18 months, the records it needs to bill toll calls: the caller’s name, address and number, plus the number called and the date, time and length of the call (47 CFR 42.6).

That covers billed toll calls only. It does not cover every call to your shop, and it does not say what your online account has to show. For anything older than your account shows, ask the company in writing what it can provide.

What the history shows, and what it does not

Expect one row per call: the date and time, the other number and how long it lasted. AT&T’s business portal also sorts calls into missed, answered and outgoing, and Verizon’s lists missed, placed and received calls.

The history shows that a call happened, not what was said. It is not a recording, and you do not need one. Florida law needs everyone’s consent to record a call (F.S. 934.03).

General information, not legal advice.

Find the calls nobody returned

Open the file in Excel or Google Sheets and go through it once, in this order:

1. 1Step 1 of 6

   Keep only the past 30 days.

2. 2Step 2 of 6

   Sort by the caller’s number, so repeat callers sit together.

3. 3Step 3 of 6

   Cross out spam, wrong numbers and calls from your own crew. Many very short calls with no voicemail are spam or hang-ups; check the number before you count it.

4. 4Step 4 of 6

   For each missed call, look for an outgoing call to that number afterward. The time between the two is your call-back time.

5. 5Step 5 of 6

   Look for a later answered call from the same number. That caller got through.

6. 6Step 6 of 6

   Mark calls after hours and on weekends apart from calls missed during the day. They need a different fix.

A missed call with no call-back after it and no later answered call is a call nobody returned.

To put a dollar figure on them, take the example numbers from our sample sheet: 14 calls missed after hours in a month, 3 of them called back.

• 14 − 3 = 11 calls nobody returned
• 11 calls × 24 percent that would have booked = 2.64 jobs
• 2.64 jobs × $151 profit a job = $399 a month

The 24 percent comes from a study of more than 3,000 trade businesses: shops with fewer than 5 technicians booked 24 percent of their calls (ServiceTitan, 2022, vendor data, US and Canada).

If you track how many of your callers book, use your own rate. Use your own numbers wherever you have them. Our article on what a missed call costs your business explains each part of the formula.

If your line keeps no history

Some lines keep none, and some owners cannot get a login. Count by hand for two weeks. Tape a sheet by the phone and write one line for every missed call, with the time and whether anyone called back.

To turn two weeks into a month, halve the count to get a week, then multiply by 52 and divide by 12. With 8 unreturned calls in two weeks, as an example: 8 ÷ 2 = 4 a week, and 4 × 52 ÷ 12 = 17.3 a month.

Put the count in the loss calculator

The loss calculator asks for three counts a week: all calls, the calls that rang out and how many of those you called back. From a 30-day list, divide each count by 4.3. It runs on your phone or computer and sends us nothing.

If you would rather hand the counting over, a walk starts from this same history. We use the past 30 days only with your written OK, from an export you run or a user seat of our own, never a shared password.

Where your phone company keeps no history, your staff keeps a hand tally by the phone for the next 30 days. See how a walk uses your call history.

Questions and answers

Where do I download my business line’s call history?

In your phone company’s online account, under call history, call logs or call detail records. AT&T Business Phone has it under Call History in the phone portal. Cox Business, now Spectrum Business, has Call Detail Records under Voice and Reports in MyAccount, for IP Centrex lines. Download the past 30 days as a CSV file where the company offers one. If you cannot find it, call the company and ask what it keeps.

How far back does call history go?

It depends on the company and the line. As of September 25, 2026: AT&T Business Phone shows the last 100 calls or the last 60 days; AT&T business cell phones, up to 16 billing cycles; Cox IP Centrex, 120 days; Verizon cell phones, up to 24 months of past bills; T-Mobile postpaid, up to one year; Quo, everything since the workspace was created.

How long do phone companies keep call records?

What you can see online is up to each company. A federal rule, 47 CFR 42.6, makes a company that offers or bills toll service keep the records it needs to bill toll calls for 18 months. It covers billed toll calls only, not every call to your shop.

Does call history record what was said?

No. It shows the date and time, the other number and how long the call lasted. AT&T’s business portal also sorts calls into missed, answered and outgoing, and Verizon’s lists missed, placed and received calls. It is not a recording. Florida law needs everyone’s consent to record a call (F.S. 934.03).

How do I find the missed calls nobody returned?

Sort the export by the caller’s number. For each missed call, look for an outgoing call to that number afterward, or a later answered call from it. The missed calls with neither are the calls nobody returned.
