IMPERITEL
Evaluate the reputation of your numbers, check them against spam databases, and verify client number validity. Reduce call failure risks and increase communication efficiency.
How we check
HLR request is a phone number validity check. It helps optimize outbound calling databases by excluding non-existent or incorrect contacts, saving time and resources.
Send a number to the chat — get the status in seconds. Handy for one-off checks.
Coordinate the check — get a notification if the number status changes.
What you learn
Spam check is an automatic monitoring of numbers in spam databases. Regular checking helps maintain a good reputation and replace numbers in time, preventing spam labels.
Use cases
Managers call clients but they don't pick up — the number is marked as spam. Check your working numbers and replace those that got into the databases.
Before launching a campaign, check all numbers in the pool. Exclude the «dirty» ones — don't waste budget on calls that won't get through.
Clients don't answer verification or support calls. Number checking helps keep your reputation in good shape.
You use a pool of numbers for outbound calls. Background monitoring — you immediately see if one of the numbers gets flagged.
