Open the call log your phone system exports and get a report on the calls nobody answered: which hours they came in, who kept trying, who got through later and how long callbacks took. The file is read in your browser and never uploaded.
In this report, an unanswered call is an inbound call that no one picked up. That includes a call that rang until it stopped, a caller who hung up before anyone answered, and a call that went to voicemail. The report counts voicemail separately from the other unanswered calls, so you can see how many callers left a message and how many left nothing.
Phone systems write these outcomes in their own words. RingCentral uses Missed, Voicemail and Hang Up, which it defines as the caller hanging up before the call was answered. Zoom Phone uses No Answer, Abandoned and Voicemail. Vonage uses Missed and Voicemail. Quo has a statusDetails column in which Abandoned and Unanswered mark calls no person answered. After you open a file, the report lists every result value it found, shows how it counted each one, and lets you change any of them.
Blocked calls, internal calls between extensions, faxes and text messages are left out, and the report says how many rows it left out and why. A few words mean different things in different systems. RingCentral uses Call connected for a call that was answered but not handled, for example by a voicemail system, and Zoom Phone uses Accepted when an auto receptionist answered rather than a person, so the report asks you how to count those. A zero-length inbound call is counted as unanswered only if you turn that rule on, because a talk time of zero does not mean the same thing in every export.
The report knows the export columns these five systems document on their own help pages, which are linked in the sources below. Export a few weeks or more, so each hour of the week has calls to compare.
Other systems can work too, when the CSV has a date and time for each call and either a result or a talk time. If the report cannot tell which column is which, it asks you to choose. An Excel workbook needs to be saved as CSV first.
The heatmap has a row for each day of the week and a column for each hour. A darker cell means more unanswered inbound calls in that hour, added up across every week in the file. Hatched cells are hours outside the business hours you set, so a dark hatched cell is calls that came in while you were closed, and a dark plain cell is calls that went unanswered while you were open.
Switch it to all inbound calls to see when the phone rings at all, and compare the two. The same numbers are in a table under the heatmap, and the busiest unanswered hours are listed in order. Times are read as the file writes them. If your export writes times in UTC, choose the time zone to convert them to.
The first panel is counted from your file and nothing else: calls in the file, inbound calls, answered calls, missed calls, voicemails, the unanswered rate, how many unanswered calls came outside your hours, repeat callers who never got an answer, callers who got through on a later call, and, when the file includes outbound calls, how long your team took to call back. A repeat caller your team reached on a later outbound call is not listed as never reached.
The estimate panel is separate and starts empty. It takes the number of callers your file shows were never reached and multiplies it by three numbers only you know: the share who were new customers, the share of those who would have booked, and your average job value. You type each one as a low and a high, and the report shows the range that follows. This tool does not use published missed-call rates; the estimate uses only your file and your numbers.
The file is read by this page in your browser, with the browser's own file reader. It is not uploaded, not saved in the browser's storage and not sent to Chleb. Closing or refreshing the page clears it.
Caller numbers are masked to their last four digits unless you choose to show them, and a printout follows the same setting.
Sending the summary to Chleb is optional and happens only when you press the send button. It sends the summary shown on screen, which is counts only, with the name, business name, email and optional phone number you type. Like every form on this site, it also sends the page you are on, the page you arrived on, the site that linked you there, any campaign tags in that link, a reference number and your browser type, and the intake keeps a one-way hash of your IP address. It is stored as an inquiry in the CRM the team works in, and a copy is emailed to the team through FormSubmit. It never sends the call log or a caller's number.
No. The page reads the file in your browser and keeps it in memory while the page is open. Nothing leaves the page unless you choose to send the summary, and the summary holds counts, not calls or numbers.
It can, if the export is a CSV with a date and time for each call and either a result or a talk time. When the report cannot tell which column is which, it asks you to choose, and it shows every result value so you can say how each one should be counted.
Not directly. Open the workbook in Excel, Numbers or Google Sheets, save or download it as CSV, then open the CSV here.
Both are calls no one answered, so both count toward the unanswered rate. They are shown separately so you can see how many callers left a message and how many did not.
Only if you press Send this summary to Chleb and fill in the form. Otherwise the report stays on your screen.
