Telephony integration
Asterisk AMI, AudioSocket, SIP/WebRTC, inbound and outbound call flows, line access, and call state.
ASTERISK · STREAMING STT/TTS · CRM
Voice AI and telephony built around the whole call
A useful voice bot is not only speech-to-text plus an LLM. I engineer the complete call path: lead selection, dialing, streaming audio, interruption handling, dialogue state, booking, retries, recordings, and the final CRM outcome.
WHAT I DELIVER
A complete working system, not an isolated code fragment.
Real-time voice pipeline
VAD, streaming STT, low-latency TTS, barge-in, echo rejection, timeouts, and graceful recovery.
Controlled dialogue
State machines, critical intent rules, LLM reasoning within boundaries, scheduling, objections, and handoff.
CRM and operations
Lead selection, deduplication, retry policies, transcripts, recordings, outcome fields, alerts, and reporting.
DELIVERY PROCESS
From an unclear workflow to a controlled release.
- 01
Map the call objective, legal and operational constraints, telephony provider, and CRM lifecycle.
- 02
Build a narrow end-to-end call path and validate audio quality before expanding the dialogue.
- 03
Test interruptions, silence, noise, voicemail, ambiguous answers, and integration failures as first-class scenarios.
- 04
Launch with monitoring and conservative limits, then improve the script from real call outcomes.

OUTBOUND VOICE AI
Telefonia: AI outbound calls connected to Bitrix24
A delivered production system for recovering missed inbound leads: it selects eligible CRM records, calls through Asterisk, holds a controlled natural-language conversation, schedules consultations, and returns the complete outcome to Bitrix24.

Useful details before we start.
Can callers interrupt the bot?+
Yes. The Telefonia pipeline included barge-in, TTS cancellation, self-echo rejection, and a return to listening.
Can the result be written to a CRM?+
Yes. I have implemented call outcomes, manager notes, facts, transcripts, recordings, and follow-up activities in Bitrix24-style workflows.
Can you improve an existing voice bot?+
Yes. I can audit latency, turn-taking, state transitions, retry logic, prompts, and CRM synchronization independently.
