How Do Ringless Voicemail Drops Work?

Ringless voicemail drops leave a voicemail on a recipient’s mobile device without the phone ever ringing. We know the result of ringless voicemail—that a voicemail is deposited into a recipient’s mailbox without the phone ringing—but how does the technology for ringless voicemail drops work?

Ringless Voicemail Drop Technology Works in 2 Ways

Most ringless voicemail providers use something they’ll ambiguously call “voicemail drop technology,” but never explain how it really works. There are two ways the technology can send a ringless voicemail to a phone. The first is to double-dial the phone number, and the second is by dialing directly into the carrier’s separate voicemail server.

Double-Dialing the Number

When a mobile phone receives two phone calls at the same time, it will usually send one of those to voicemail and in most cases drops the other call due to the disruption in the network. This allows one of the two calls to leave a voicemail message without the phone ever ringing. This method sometimes leaves a “missed call” alert on the recipient’s phone.

Ringless voicemail providers using this method typically utilize a system that automates the dual dial in perfect synchronicity. These systems also automate the send of pre-recorded voicemail messages that make ringless voicemail so alluring for marketers.

Dialing into the Carrier’s Voicemail Server

While it may feel like your voicemails are stored directly on your mobile device, they’re actually stored on your wireless network’s server. When someone calls your phone number and you don’t answer, they are routed via a separate phone number to one of your wireless carrier’s servers, which hosts the voicemail and syncs with your mobile device.

Some ringless voicemail providers dial directly this server to then drop a prerecorded voicemail directly in the mobile user’s voicemail inbox.

Which ringless voicemail technology is best?

Since both methods end with nearly the same result, the actual technology being used does not usually make a difference to the end user. One minor difference is that the double-dial may occasionally leave a missed call on the recipient’s device. Some marketers want to completely avoid this possibility, while others don’t mind the occasional missed call alert since it can sometimes make the voicemail message seem more genuine.

How do I send a ringless voicemail?

There are multiple ringless voicemail services that allow you to record and send a ringless voicemail from an online dashboard. Your voicemail can be sent to a small number of recipients or can be sent to hundreds or even thousands of mobile phone users.

When choosing a ringless voicemail provider, we recommend choosing one that has a low cost- per-message. Be sure to also choose a company that doesn’t charge for undelivered messages. Failed ringless voicemail sends may occur for a few reasons. You may experience a soft bounce where a temporary network issue prevents a successful send. In these cases, some ringless voicemail systems will retry a second time. Hard bounces are sends that are unsuccessful due to an incorrect or disconnected phone number.
