* The call reaches the final destination through another copyright.
Every minute of traffic generates revenue based on the difference between buying and selling prices.

* Profit = $0.002 per minute.
Although the profit margin per minute appears small, wholesale companies often process millions of minutes every month.
For instance:
* 5 million minutes/month
* Profit per minute: $0.002
Monthly gross profit:
5,000,000 × 0.002 = $10,000
As traffic volume increases, profitability grows substantially.
