The short version
- Look at the outcome first. Did the customer get their problem solved, get accurate information, and get treated with respect?
- Keep your scorecard to a few clear items. A long checklist gets applied differently by every reviewer.
- Reading across a batch of transcripts shows you which customer problems keep coming up.
- Support calls contain personal data. Tell people when a call is recorded, limit who has access, and keep recordings only as long as you need them.
- Call recording and privacy rules vary by country. Check with your legal adviser, and check the audio before relying on an automated transcript.
What is a support call review for?
Reviewing support calls does two things for a team. For individual agents, it replaces vague feedback with specific moments from real calls they can learn from. For the wider company, looking across calls shows what customers actually struggle with: which problems come up all the time, which explanations confuse people, and which parts of the product keep driving people to call support.
Almost nobody has time to sit and listen to every call from start to finish. If you have a transcript alongside the audio, a reviewer can scan a call in two or three minutes, find the part that matters, and listen to just that stretch. That makes it realistic to check more calls and to review them sooner, while the ticket is still open.
How do you protect customer privacy?
Start by telling callers they are being recorded. Usually this is a short notice at the beginning of the call saying it's recorded for quality and training. Because recording laws differ from country to country and depend on the context, and because Israel's call recording regulations are changing, ask your legal adviser what applies to your work and write those rules into your procedure.
People regularly give out identity numbers, addresses, and account details on support calls, and sometimes payment or health information too. Decide upfront what should never be recorded or stored, and tell agents to take sensitive details over an unrecorded channel when your policy requires it. Limit transcript access to the people actually doing reviews, set a clear retention period, and delete records on request where regulations require it.
Make sure you know how your tools handle audio. KolWrite lays out how it works on its security page, including encrypted connections, AES-256 storage, servers in Germany, named AI providers, and no AI training on customer content.
What should a quality scorecard include?
Keep your scorecard to five or six questions built around what the customer experienced. Did the agent understand the problem within the first few minutes? Was the information they gave accurate and complete? Did they clearly explain the next step and give a timeframe? Did the agent stay calm and respectful, even if the customer wasn't? Did they follow required procedures, like verifying identity or reading a disclosure? And was the case closed or handed over properly?
Write a short definition for each item on the scorecard, along with two examples from real calls: one strong, one weak. Without real examples, two reviewers will grade the same call differently, and agents will figure out pretty quickly that their score depends on who happened to review them.
Grade the call itself, not the agent personally. When a bad call comes down to a product bug or a company policy the agent has no control over, log it as a problem for the company to fix rather than marking the agent down.
How do you find recurring problems?
One call is an anecdote, while a group of transcripts gives you real data. Read through a batch of calls from a single week and tag each one with the reason the person reached out, sticking to a short list of categories you've set up. After a few dozen calls, the top three or four problems usually jump out. Those point to things you can fix at the source, like a confusing error message, a missing help article, or a delayed process.
Being able to search the text speeds this up. In KolWrite, you can search a transcript for a specific word and click straight to that exact second in the audio. That makes it quick to check how a customer phrased a problem or whether an agent explained something right. When you write help articles, use the exact words customers use on the phone, since that is what other people will type into your search bar.
Pass what you find on to the teams that can actually fix things: product, operations, and documentation. If your quality program only grades agents, you are missing out on the most useful part of the work.
How do you run reviews week to week?
Pick a sample of calls for each agent that covers different lengths, topics, and outcomes, including both high and low customer ratings. Read the transcript, mark the important parts, and listen to the audio for those sections. Write down a timestamp for every note on the scorecard so the agent can go back and hear the exact part you heard.
Get your reviewers on the same page regularly. Once a month, have everyone score the same three calls on their own and compare notes. Wherever they disagree, your scorecard definitions are probably too vague, so tighten up the definitions rather than blaming the reviewers.
Remember that automated transcripts make mistakes. Phone lines have limited bandwidth and plenty of background noise, so names, product codes, and numbers often get mangled. Use the transcript to find the right spot in the call, then listen to the audio before you judge how the agent handled it.
How do you give feedback that agents can use?
Play a short clip of ten to twenty seconds and describe what you hear before giving your judgment. Ask the agent what was going through their head at that moment, then agree on one specific behavior to practice. Always point out something the agent did well and explain why it worked, since specific praise teaches just as much as correcting a mistake.
Tie the review work back to the customer experience whenever you can. When a pattern you spotted in call reviews gets a product bug fixed or a bad policy changed, tell the team about it. Agents take reviews a lot better when they can see the process making their day-to-day job easier.
Common questions
How many support calls should be reviewed?
Review enough calls to spot recurring problems and give every agent regular feedback. Even a small weekly sample per agent works well, as long as reviewers grade consistently with the same scorecard.
Can transcripts replace listening to calls?
Transcripts save time by showing you which parts of a call to check, but you still have to listen to the audio to hear tone, hesitation, and sarcasm.
What should never be recorded in a support call?
That depends on your company policy and what your legal adviser tells you. Companies commonly have agents collect sensitive details, like payment information, through a separate channel that isn't recorded.
How do we use calls to improve our help content?
Tag calls by why the customer reached out, see which issues come up the most, and write your help articles using the exact phrasing customers used on the phone.
Does KolWrite join live calls?
No. You upload the recording after the call is over. KolWrite does not provide live captions during a call.
