1. Prompt the Agent to Recognize Phone Screening Language

AI voice agents should be explicitly prompted to recognize common phone screening prompts and switch their behavior when those prompts occur.

Phone screening systems typically play a message asking the caller to state their name and reason for calling before the phone rings the user.

Some of the most common examples today include:

iOS / Apple Call Screening

“Hi, record your name and reason for calling. I’ll see if this person is available.”

Android / Google Pixel Call Screen

“Hi, I’m an automated call assistant recording this call for the person you are trying to reach. Can I ask what you are calling about?”

Your AI agent should be prompted to recognize phrases similar to these, such as:

• “Record your name and reason for calling”
• “Please state your name”
• “Say who is calling”
• “What are you calling about?”
• “I’m an automated assistant recording this call”

Once the agent detects language like this, it should immediately stop its normal opening script and switch to a short screening-safe response.

Recommended response format:

“Hi, this is [Agent Name] calling with [Company Name] to discuss [short reason].”

Example:

“Hi, this is June calling with SalesAi to discuss your recent inquiry.”

The response should remain:

• short
• clear
• professional
• easy for screening systems to process

Avoid long explanations or full sales pitches during this moment. The purpose of the response is simply to identify who is calling and why so the screening system can pass the call through to the recipient.

It is also important to note that these screening messages may change at any time as Apple, Google, and carriers update their software. Agents should therefore be prompted to recognize the general pattern of screening prompts rather than relying on only one exact phrase.

2. Encourage Number Recognition and Saved Contacts

One important detail is that saved contacts often bypass phone screening systems entirely. Most screening tools are designed to filter unknown callers. When the calling number is already saved in the user’s phone, the call will usually ring directly to the person without triggering a screening prompt.

Because of this, organizations should actively encourage prospects and customers to save the number that will be calling them.

This can be done during several moments in the customer journey, including:

• During sales conversations
• During onboarding calls
• In customer success or support interactions
• In follow-up emails or onboarding documentation

For example, a sales or onboarding conversation might include a simple instruction such as:

“If you’re able to, it may help to save this number in your contacts so our agent can reach you easily when we follow up.”

3. Pre-Warm the Prospect So They Expect the Call

One of the most effective ways to reduce phone screening tools as a blocker is to make sure the prospect expects the call.

When someone receives a call they were not anticipating, they are far more likely to rely on screening tools. However, when the call is expected, people are much more likely to answer directly.

Pre-warming can happen at multiple points in the customer journey, including:

• Immediately after someone fills out a form
• On a form submission confirmation page
• In follow-up emails
• During CX and Onboarding conversations
• In website messaging for inbound leads

The goal is to clearly communicate that a follow-up call will occur and who the call will come from.

Example messaging could include:

“Keep an eye out for a quick call from June at (xxx) xxx-xxxx regarding your request.”

“You may receive a call from our agent June at (xxx) xxx-xxxx to help with next steps.”

“After submitting this form, expect a quick follow-up call from our team.”

When the prospect recognizes the company, agent name, or phone number, they are much more likely to answer the call instead of relying on phone screening.

4. Test a Double-Call Strategy

In some cases, a second call placed shortly after a screened call may ring directly to the prospect.

Certain screening systems treat repeat calls differently. After the first call is screened, a second call may bypass the screening system and ring through to the recipient.

Because of this behavior, it can be helpful to test a double-call strategy when appropriate.

Example workflow:

Call attempt one → screening system answers
Short delay → second call attempt

In some situations, the second call may reach the prospect directly.

However, this tactic does not work in all situations. Its effectiveness can depend on several factors including the carrier being used and system updates.

Because these systems evolve over time, this approach should be treated as an optional tactic to test rather than a guaranteed solution.
