No need to fly blind with the help of robust portal reporting

Number Sentinel phone management software ensures you can have ongoing visibility of your numbers through the management platform. This means you will not only get insight into how your numbers are being labeled, but also have the ability to mitigate those labels and adjust your dialing practices as necessary. Additionally, the Number Sentinel tool maps your number – so if the customer is more likely to answer a local number or a toll-free number, that number will be used for the outbound calls, ensuring you reach as many customers as possible.

What our clients are saying

“Prior to advanced number management, we were using large generic outbound number pools. Now, [Number Sentinel] has allowed us to obtain custom numbers based on the portfolios, along with branding them, while keeping spam labeling low. The result was an immediate 25% lift in connect rates. By adding the Map & Manage feature to ensure every call originated from a clean number, we further improved overall performance percentage to over 30% and it strengthened our position as the top-ranked vendor for the creditor.”
