First, your idea. Think about the service or information you'd like to offer. If you plan to have representatives or consultants handle the calls live, think about how many you would need. Our Advanced Features can route calls almost any way you need to. If your service only attracts callers from certain regions, you can limit your service to certain areas.
Advanced Features can help here, too.
Naturally, to attract callers to your 900 application, they have to know about it. Think about where and how you will spread the word about your service. Newspaper ads, magazines, direct mail, radio, TV, billboards, the Internet and catalogs are possibilities. It all depends on who your audience is and where you're likely to find them. Think about your available budget.
