Why Members Aren't Receiving Calls (and How to Fix It)
If a member of your group states they are not receiving your phone calls, it is usually caused by one of three blocking barriers. Follow this guide to identify and resolve the issue.
1. Blocked via the CallingPost System
If a member accidentally or intentionally used our automated opt-out system during a previous call, their phone number will appear highlighted in Red on your group contact list.
How to Fix It: For security and compliance, the owner of the phone line must opt themselves back in. The member can call CallingPost Customer Care directly at 877-665-5646 from the blocked phone line to request an opt-in.
Alternative Option: They can call back any Oklahoma City Caller ID number (e.g., 405-308-XXXX, 405-669-XXXX, or 405-754-XXXX) from their phone and follow the automated interactive prompts to manually unblock themselves.
2. Blocked or Filtered on their Personal Device
If the member's number is active on your contact list, but calls aren't coming through, their smartphone or carrier spam feature may be filtering out unknown caller IDs.
For iPhone Users:
Open Settings and tap Phone.
Tap Blocked Contacts. Check for any blocked CallingPost numbers or Oklahoma City prefixes (405-308, 405-669, or 405-754), tap Edit, and select Unblock.
Check Silence Unknown Callers (Settings > Phone). If enabled, calls from rotated pool numbers not saved in their contacts will send directly to voicemail without ringing the phone.
For Android Users:
Open the Phone app, tap the Menu (three dots), and select Settings.
Tap Block Numbers. Locate any CallingPost numbers or local Oklahoma City prefixes and tap the minus icon or trashcan to remove them.
Check Caller ID & Spam. If active, verify that high-risk spam blocking isn't silently routing unrecognized numbers straight to voicemail.
3. Carrier Spam Filtering & "Silent Voicemail" Routing
To maintain high delivery rates and bypass carrier congestion, CallingPost rotates broadcasts across 290+ local Oklahoma City default Caller IDs. Occasionally, an over-aggressive mobile carrier filter (e.g., AT&T, Verizon, T-Mobile) or spam application (like Hiya or Robokiller) may flag one of these rotated lines.
What You & Your Members Experience:
Legacy Disconnects: The carrier blocks the connection entirely, causing your broadcast report to show an "Intercept" or "Busy" status.
Carrier "Soft-Blocks" (Silent Spam Voicemail): Mobile carriers often deliver the call directly to the recipient's voicemail without ringing their phone or creating a missed call notification. Because our system successfully connects to the carrier's automated voicemail greeting, your report will indicate "Answering Machine." The recording resides in the recipient's hidden "Spam" or "Junk" voicemail folder, so the member is unaware a message was left.
System Action:
Individual Reports: If a member states they missed a call that shows as "Answering Machine" in your report, ask them to check their phone's Junk/Spam Voicemail folder or mark the CallingPost caller ID as "Not Spam."
Massive Spikes: If you notice a widespread, sudden spike of Intercepts, Busys, or uncharacteristic Answering Machine statuses across a large percentage of your list during a broadcast, contact us immediately at 877-665-5646 so our network engineering team can audit and re-route the carrier line.
