What to Expect
Ringless voicemail (RVM) allows you to drop a message directly into a recipient’s voicemail box—without ringing their phone. However, delivery isn’t guaranteed. On average, you can expect about an 80% success rate, due to factors outside of our control.
Why a Voicemail May Be Delayed or Missing
1. Carrier Filtering or Blocking
Carriers may block or delay delivery if:
You send multiple drops to the same number in a short timeframe
The number is VOIP or a landline (not compatible with RVM)
The voicemail is flagged as spam due to content or frequency
2. Voicemail Box Issues
Voicemail won’t be delivered if:
The inbox is full
Voicemail is not set up
The recipient’s carrier has disabled voicemail
3. Phone Status and Network Conditions
If the recipient's phone is:
Powered off
Out of network range
On airplane mode or Wi-Fi only
Then the voicemail may be delayed—or silently dropped.
4. Device and Carrier Variability
Some devices (e.g., iPhones) and carriers (especially smaller or regional ones) may handle RVM delivery differently. Delays of several minutes or even hours are not uncommon.
Test Feature Limitations
When using the Test Voicemail tool:
You can only test once per number every 24 hours
Additional attempts may be blocked by the carrier
Important Note: Ringless voicemail systems are designed for high-volume delivery, and one-off test drops are more likely to fail due to how carriers handle isolated attempts. Testing your own number can also be unreliable, especially if you're using Wi-Fi or a device with stricter spam protections.
Best Practices for Reliable Delivery
Use valid mobile numbers only (not VOIP or landline)
Ensure the voicemail inbox is set up and not full
Keep the phone powered on and connected to mobile data
Wait 24 hours between test attempts to avoid triggering carrier blocks
Avoid spammy phrases or URLs in your voicemail message
Tip: Call your own number and let it ring without answering to see how long it takes to reach your voicemail. Most carriers route unanswered calls to voicemail after 15 to 25 seconds. This test helps confirm that your voicemail is set up properly and provides an indication of how long delivery might take in a typical drop.
