Finding Why a Customer's Agents Kept Getting Busy Tones

The Starting Point

The customer's agents kept getting busy tones when they called back. From the customer's side it looked like dropped calls, with no clear reason.

What I Did

I went back through the account's history to see how the lines had been set up and changed over time. That showed their line limit was being miscounted, so calls were hitting the limit before they should have.

I passed it to engineering with what I had found, and they fixed how the lines were counted.

The customer was then told how many lines they have, so they know what to expect when their agents are busy.

What Went Into the Work

Why It Matters

The customer's agents could not reach the people they were calling back.

Finding the cause in the account history meant engineering could fix the counting, and the customer got a clear answer about how many lines they have.

Tools and Skills Used

Technical troubleshooting, account investigation, clear escalation to engineering and plain explanations for customers.

Who This Is For

This case study is worth reading if you are:

• ●A telecom or VoIP provider whose support tickets stall because nobody finds the cause.
• ●A support lead who wants tickets escalated with evidence, not just the customer's complaint.
• ●Looking for someone who digs into the account before guessing at a fix.
