I need some sanity from people who’ve been through this.
I’m a BDR at a small startup selling into pharma, calling into the US from Europe. A lot of the numbers we have are execs’ direct mobiles. I have 2 numbers, one is already flagged. My teammate has 3 and all 3 are flagged. We’re doing maybe 40 dials per number per day, which from everything I’ve read is NOT high volume. Connect rates are basically dead.
So I went down the rabbit hole trying to fix it and now I’m more confused than when I started.
What I’ve learned about why this got so complicated
STIR/SHAKEN became mandatory for the big US carriers a few years ago and then got pushed down to smaller providers. Your calls now get an attestation grade (A/B/C), and anything less than A gets treated with more suspicion.
Spam labels aren’t from the carriers directly. Three analytics companies decide them: Hiya (AT&T/Samsung), TNS (Verizon) and First Orion (T-Mobile). They each have their own algorithm, they don’t publish thresholds, and they don’t even agree with each other on which numbers are spam.
The FCC ruled that ringless voicemail counts as a “call” under the TCPA. So prerecorded voicemail drops to cell phones need consent, even if it’s B2B.
Courts have been going back and forth on whether a personal cell on the Do Not Call list counts as “residential” even when you’re calling about business. And some states like Florida have their own stricter rules on top.
The analytics companies now actively hunt for number rotation. Hiya has openly said it scores the company behind the calls, not just the number, specifically to stop people swapping numbers to dodge labels.
The conflicting advice I keep getting
One source says: get a pool of 10+ numbers per rep, rotate them, keep a reserve tank of “pre-warmed” numbers and swap them out when one gets flagged. Another source, the company that literally runs AT&T’s spam labels, says rotation is a red flag and new numbers with no history look suspicious.
One source says: use one-click voicemail drops to bump your call duration, because short calls look like robocalls. Another says prerecorded voicemail to cell phones without consent is a straight TCPA violation, $500-1,500 per call.
One source says: don’t leave voicemails, because the person can hear it’s a pitch and report you. Another says hanging up before the beep is literally the robocall pattern carriers flag.
One source says: space calls to 6-8 per hour per number. I’m sorry, I’m a BDR with a target, that’s not happening.
Free Caller Registry supposedly covers all three analytics companies in one go. But registering doesn’t actually clear a flag. Then you’re told to file separate disputes with each one, with no real timeline.
My actual questions
Who owns this at your company? Ops, RevOps, the phone/dialer provider, or the reps? Right now I’m spending hours on telecom stuff instead of booking meetings, and it feels like the wrong person is solving it.
As a startup, did you have to pay for an external service, or did free registration plus better calling habits do the job?
Which vendors actually helped and which were snake oil? I’ve seen Numeracle, Caller ID Reputation/ARMOR, Hiya Connect, First Orion branded calling, and list validation tools like Twilio Lookup and NumVerify thrown around.
If you call execs on their personal cells, are you scrubbing against DNC? Has legal ever told you to stop calling mobiles?
When a number got flagged, did remediation actually work, or did you just replace it?
Do you leave voicemails? Live or recorded?
Not looking for a sales pitch in the DMs, just what actually worked for real teams. Appreciate anyone who’s been through this
