CallerGuardian
Someone should be watching your numbers. We are.
Numbers get flagged. It’s the nature of outbound. Most dialers don’t even tell you when it happens. CallerGuardian places real test calls on every major US carrier and rotates flagged numbers out automatically — before your answer rates take the hit.

Continuous monitoring
How it works
Monitor. Detect. Replace.
CallerGuardian runs continuously behind the scenes. No dashboards to check, no numbers to manage, no manual rotation.
Place real test calls
CallerGuardian calls real cell phones on AT&T, Verizon, and T-Mobile — the same networks your prospects use. Not an API check. A real call.
Monitor number health
Carrier spam flags are just the start. CallerGuardian also tracks failed calls, answer rate trends, and other health signals to detect numbers going bad — even before carriers flag them.
Replace automatically
Flagged numbers are pulled from rotation and replaced with clean numbers from your pool — instantly. No ticket, no wait, no manual swap.
The problem
Your numbers are flagged. You just don’t know it.
After a few hundred outbound calls, carriers start flagging your numbers as spam. Your prospects see “Spam Likely” on their screen and don’t pick up. Your answer rates crater — and most dialers never tell you.
By the time you realize something’s wrong, you’ve already burned through your list calling from flagged numbers. That’s hundreds of prospects who will never pick up.
81% of sales professionals say their company loses revenue due to spam flags.
The average outbound team has no idea which numbers are flagged until answer rates collapse.
CallerGuardian catches flagged numbers before your prospects do. Automatic. Continuous. No manual work.

Nobody picks up — you don’t know why

Features
Everything that keeps your numbers clean
Real carrier test calls
Not an API lookup — CallerGuardian places actual phone calls on AT&T, Verizon, and T-Mobile networks. We see exactly what your prospects see when your number shows up on their screen.
Automatic number rotation
When a number is flagged, it's pulled from your active pool and replaced with a clean number. No manual swaps, no support tickets — it just happens.
Carrier registration
Your numbers are pre-registered with major carriers as legitimate business numbers — reducing the risk of false flags before you ever make a single call. Prevention first, detection second.
Multi-signal detection
We don’t rely on a single data point. CallerGuardian cross-references carrier test calls, spam databases, failed call rates, and answer rate trends to catch unhealthy numbers from every angle.
Built for LocalEdge
CallerGuardian is designed to work with your LocalEdge number pool. It monitors your entire inventory of US local numbers and keeps the pool as clean as possible — so LocalEdge always has fresh numbers ready.
STIR/SHAKEN compliance
All numbers carry proper STIR/SHAKEN attestation and 10DLC registration. CallerGuardian works within the compliance framework — not around it — to give your numbers the best possible reputation.
Why it matters
Flagged numbers hurt every minute they’re active
Most providers make you wait on carrier disputes before you can do anything. Your numbers stay flagged the entire time, and your answer rates stay in the gutter. CallerGuardian rotates flagged numbers out immediately so your team keeps dialing — while we handle remediation in the background.
Traditional remediation
File carrier disputes manually
Each carrier has a different process
Wait 1–14 days for resolution
Numbers stay flagged the entire time
No guarantee of removal
Carriers can deny the dispute
Every call from a flagged number is a wasted dial
CallerGuardian
Detect and replace automatically
No tickets, no manual swaps
Clean replacement from your pool
Pre-registered, carrier-verified numbers
Zero downtime on your answer rates
No waiting for carrier approvals
Rotate now, remediate in the background — your team never misses a beat
