​

Core Concepts

​

Agent

AI voice assistant that handles conversations autonomously. Configured with a system prompt, LLM, voice, and optionally tools. Agents can receive inbound calls and make outbound calls.

​

Conversation

Single interaction between an agent and a person. Each conversation has a unique ID and produces a transcript.

​

Tool

Action an agent can take mid-conversation. Tools call your API to perform operations like checking order status, booking appointments, or looking up customer data. Defined with JSON Schema for parameters.

​

Webhook

HTTP notification sent to your server when events occur. Events include call started, call ended, tool execution requested, and transcription updates.

​

Voice & Speech

​

TTS (Text-to-Speech)

Technology that converts agent text responses into spoken audio. Dasha BlackBox supports multiple providers: ElevenLabs, Cartesia, Inworld, and LMNT.

​

STT (Speech-to-Text)

Also called ASR (Automatic Speech Recognition). Converts caller speech into text that the agent can process. Handles accents, background noise, and real-time transcription.

​

ASR (Automatic Speech Recognition)

See STT. The technology that transcribes spoken words into text.

​

Voice ID

Identifier for a specific voice within a TTS provider. Each provider offers different voices with varying characteristics.

​

Pronunciation Dictionary

Custom rules for how the agent pronounces specific words. Useful for brand names, technical terms, and uncommon words.

---

​

LLM Configuration

​

LLM (Large Language Model)

AI model that generates agent responses. Dasha BlackBox supports OpenAI, Anthropic, Google, Azure, Groq, and Reflex-1 models.

​

Reflex-1

Dasha’s in-house LLM optimized for real-time voice conversations with very fast response times.

​

System Prompt

Instructions that define agent behavior, personality, and capabilities. The foundation of agent configuration.

​

Temperature

LLM setting controlling response randomness. Lower values (0.3-0.5) produce consistent responses; higher values (0.7-0.9) produce more varied responses.

---

​

Telephony

​

SIP (Session Initiation Protocol)

Standard protocol for voice calls over internet. Used for connecting to phone systems.

​

SIP Trunk

Connection between Dasha BlackBox and your phone system. Enables inbound and outbound calls through your existing phone numbers.

​

SIP Credentials

Organization-level authentication settings for your SIP trunk provider. Stores server address, username, password, and transport protocol. Multiple phone numbers can share the same credentials.

​

Twilio Provider

Managed SIP integration that automatically creates and configures SIP trunks. Simplifies setup by handling credential management and phone number provisioning through your Twilio account.

​

CPS (Calls Per Second)

Rate limit for simultaneous call attempts through a SIP trunk. Configured via cpsLimit to prevent overloading your telephony provider.

​

E.164 Format

International phone number format. Includes country code with + prefix: +12025551234.

​

IVR (Interactive Voice Response)

Automated phone menu system (“Press 1 for sales”). Dasha BlackBox agents can detect and navigate IVR systems during outbound calls.

​

DTMF (Dual-Tone Multi-Frequency)

Touch-tone signals generated when pressing phone keys. Used for navigating phone menus.

​

Call Handling

​

Inbound Call

Call received by the agent. Caller dials a phone number connected to your agent.

​

Outbound Call

Call initiated by the agent. Scheduled via API to contact a recipient.

​

Phone Number Linking

Connecting a phone number to an agent. Use inbound mode for receiving calls or replaceOutbound mode for caller ID on outgoing calls.

​

Caller ID

Phone number displayed to recipients during outbound calls. Set by linking a phone number with replaceOutbound mode.

​

Call Priority

Priority level for outbound calls: low, medium, high, or critical. Higher priority calls are processed first in the queue.

​

Business Hours

Schedule defining when an agent accepts inbound calls. Calls outside business hours can be rejected or handled differently.

​

Warm Transfer

Transfer where the agent briefs the human operator before connecting the caller. Operator receives context about the conversation.

​

Three-Way Announcement

Message played to the caller during warm transfer while the agent briefs the operator. Can be static text or dynamically generated using smartV1 mode.

​

Cold Transfer

Direct transfer to a human operator without briefing. Faster but requires caller to re-explain their situation.

​

HTTP Transfer

Dynamic transfer routing via webhook. Your server determines the transfer destination based on real-time data.

​

Call Recording

Audio recording of the conversation. Enabled per-agent and stored for later review.

​

Pre-Conversation Media

Audio file played before the agent speaks. Configured separately for inbound, outbound, and web calls. Useful for greetings, disclaimers, or hold music.

​

Noise Suppression

Krisp-powered audio filtering that removes background noise from calls. Configured with a level from 0 (off) to 100 (maximum). Incurs additional per-minute fee.

---

​

Integrations

​

MCP (Model Context Protocol)

Protocol for connecting external data sources and tools to agents. Enables dynamic capabilities without custom webhook development.

​

Knowledge Base

External information source connected to an agent. Agents can query knowledge bases to answer questions beyond their system prompt.

---

​

Web Integrations

​

Web Integration

Configuration for embedding agents in websites. Includes allowed origins, enabled features (voice/chat), and widget appearance settings.

​

Widget

Embeddable UI component for your website. Provides voice or chat interaction with your agent directly in the browser.

​

WebSocket

Real-time communication protocol used for web voice calls and chat. Enables bidirectional streaming of audio and messages.

​

Access Token

Short-lived credential for authenticating WebSocket connections. Generated via API and passed to the widget for secure access.

---

​

Monitoring

​

Activity Logs

System events tracked for debugging and auditing. Includes call events, tool executions, errors, and warnings. Searchable by event type, severity, agent, and date range.

---

​

Events & Notifications

​

StartWebHookPayload

Webhook sent when a call begins. Can include custom data from the caller.

​

CompletedWebHookPayload

Webhook sent when a call ends. Contains transcript, call duration, and result data.

​

ToolWebHookPayload

Webhook requesting tool execution. Your server performs the action and returns the result.

---

​

Performance

​

Latency

Time between user speech and agent response. Target is under 2 seconds for natural conversation.

​

Concurrency

Number of simultaneous active calls. Limited by account tier.

​

Rate Limiting

API request limits to prevent abuse. Tracked per endpoint with retry guidance.

---

​

Account

​

Organization

Top-level account container. Holds all agents, integrations, and team members.

​

API Key

Authentication credential for API access. Starts with bb_. Keep secret and never expose in client-side code.
