How do I handle anonymous calls without losing any leads?

The issue with anonymous calls

Many businesses face an important dilemma with anonymous calls. Most of them are low-quality, or spam calls. Still, there is a good amount of potential in them, as many actual leads, for their own reasons, prefer to call anonymously.

Blocking, anonymous calls is easy, but doing that might cost you leads. So, let's see how you can minimize worthless anonymous calls, without hurting your business.

How to set up a call flow for anonymous calls

The best thing you can do is design a call flow that will automatically play a voicemail for anonymous calls. Callers will hear a message that will ask them to call again from a regular phone number. To do that:

Step 1. Head over to Tracking > Call Flows and click on the ' + Add' button to create a new call flow.

Step 2. Click on the '+' plus button and select the Caller ID prefix filter from the right-hand side call-flow actions menu.

Step 3. Type 'anonymous' on one of two Caller ID Prefix paths that have been created and leave the other as is.

Step 4. Click on the '+' plus button and select the 'Voicemail' routing option on the anonymous path.

Step 5. Complete the second path by routing all other calls to the destination(s) of your preference.

And that's it! Now, callers who call with genuine interest will know that they need to call back with their phone number visible, while robocalls, spammers and low quality calls will remain away.
