Overview

This page outlines how Callers categorizes call statuses based on telephony data, real-time analysis, and post-call processing. Each status is determined by specific criteria, as detailed below.

No Answer / Busy

No Answer and Busy statuses
Description: These statuses reflect the outcome of telephony connectivity attempts. Source: Received directly from Twilio or SIP providers via standard SIP response codes (e.g., 408 for No Answer, 486 for Busy) Processing: No modifications are applied; these statuses are logged as provided by the telephony layer.

Voicemail

Voicemail status
Description: Indicates the call reached a voicemail system rather than a live person. Detection methods:
  • Twilio Identification: Twilio flags the call as voicemail based on its telephony signaling.
  • Real-Time Transcript Analysis: During the call, Callers analyzes the audio transcript in real-time using proprietary models to identify voicemail patterns (e.g., automated greetings, beeps, or extended silence).
  • Post-Call Transcript Review: After the call ends, the full transcript is re-analyzed to retroactively confirm or classify it as voicemail based on content (e.g., phrases like “leave a message”).
Model Improvement: Detection models are continuously refined using real-world call data to enhance accuracy over time.

Do Not Call

Do Not Call status
Description: Assigned when the recipient explicitly requests no further contact. Criteria: Triggered by clear statements such as “never call me again,” “remove me from your list,” or similar unambiguous requests. Processing: Once identified, the number is flagged to prevent future calls.

Wrong Number

Wrong Number status
Description: Indicates the call reached an incorrect or unintended recipient. Criteria: Applied when the recipient explicitly states “this is the wrong number,” “you have the wrong person,” or equivalent phrasing. Processing: Logged based solely on the recipient’s response.

Call Me Later

Call Me Later status
Description: Suggests the recipient is unavailable now but open to a future call. Criteria:
  • Explicit request: The recipient says they cannot speak currently and requests a later call (e.g., “call me tomorrow,” “try me later”).
  • No meaningful engagement: When there is no genuine two-way exchange, the call defaults to “Call Me Later” to preserve potential future availability. The exact cases are listed in the Call Me Later vs Not Interested table below.
Processing: Marked for follow-up based on these conditions.

Interested / Not Interested

Interested and Not Interested statuses
Description: Assigned to connected calls that do not fall into the above categories, indicating the recipient’s level of interest. Criteria:
  • Applies to calls that successfully connect (i.e., not “No Answer” or “Busy”) and are not classified as “Voicemail,” “Do Not Call,” “Wrong Number,” or “Call Me Later.”
  • For genuine two-way conversations, classification as “Interested” or “Not Interested” is determined by the AI classifier against predefined interest criteria specific to the campaign (e.g., engagement level, intent signals).
  • A call is also marked “Not Interested” when the recipient disengages by action rather than words — see the Call Me Later vs Not Interested table below.
Processing: Evaluated based on the conversation content and campaign goals.

Call Me Later vs Not Interested

When a lead does not really engage, the deciding factor between Call Me Later and Not Interested is usually how the call ended: a call that drops on its own leans toward Call Me Later, while the lead actively hanging up leans toward Not Interested. Longer, two-way conversations are always handed to the AI classifier.
