“We tried three cloud phone tools before this one. The reason we stayed is boring — it just kept working across four time zones. Our sales team stopped thinking about the phone.”

FAQ
OTP pumping protection FAQs
What is OTP pumping fraud?expand_more
OTP pumping, also called SMS pumping or artificially inflated traffic, is when fraudsters trigger large waves of fake one-time code requests toward number ranges they profit from. The business pays for every message, and nobody is actually signing in.
How does OTP Pumping Guard detect pumping?expand_more
MCM AI watches request patterns, destinations and timing. A sudden wave of code requests to unusual number ranges, with no matching real sign-ups, is scored as high risk and flagged. It covers one-time codes sent by SMS and voice.
Will real users miss their codes?expand_more
No. MCM AI blocks the pumped traffic and keeps genuine login codes flowing. When a range is slowed or blocked, smart checks still let real users in that range through.
What happens to a number range that gets pumped?expand_more
When a range starts pulling strange volumes of codes, MCM AI slows it first and blocks it if the pattern continues. Range level controls let your team tune how strict the guard is.
Can enterprise customers see the results?expand_more
Yes. Brands get clear, shareable reports showing which apps were targeted, which ranges were blocked and how their traffic changed, so they stop paying for traffic nobody wanted.
Can I resell OTP Pumping Guard under my own brand?expand_more
Yes. OTP Pumping Guard is white-label, so operators and carriers can launch it for enterprise customers with their own logo on every screen and report.
