Imagine Farhan, who runs the sales desk of a travel agency in Dubai with six telecallers working holiday enquiries. On a normal day the desk makes about 480 calls, roughly 80 per person.
One week the analytics rings show a caller at 80 calls a day but only 20 connected, against a desk average of about 50. The call log explains it: most of that caller's list came from an old trade-fair register, and almost nobody on it picked up.
The same week another caller looks quiet on SIM calls, until the log shows twelve WhatsApp video calls with families comparing packages. Farhan moves the first caller onto fresh website enquiries and leaves the second alone. Without the internet calls in the log, both would have read as slow.
