AI Voice Agents

Connect Your AI Voice Agent to
3CX & Yeastar

Your AI agent answers the call — then transfers to a real person on your 3CX or Yeastar, or SMS’s your team, straight over SIP URI. No extra SIP provider, no per-minute transfer cost, and no code.

The problem

AI agents disconnected from your phone system

Most AI voice platforms treat your phone system like an afterthought.

Every call your AI can’t handle becomes a hang-up. Unless it can hand callers off to a real person on the phone system you already run, it’s pointless — so we give it a direct line into your 3CX or Yeastar to transfer calls and message your team.

The fix

Transfer calls & send SMS — through your existing 3CX or Yeastar

Give the agent a SIP URI into your phone system. It answers, then hands off to a real person — and can message staff — all on the 3CX or Yeastar you already run.

Transfer to any extension or queue

The agent uses an outgoing SIP URI trunk into your 3CX or Yeastar and blind-transfers the caller to the right person, group or queue.

SMS your team

When someone’s unavailable, the agent can text a user or a whole queue on 3CX or Yeastar — so the right person always gets the callback request.

No transfer cost, no extra provider

It runs over your existing 3CX or Yeastar SIP trunk — no second SIP provider and no per-minute transfer charges. No code required.

Works on any SIP PBX

On 3CX, Yeastar, or another platform — the exact same SIP URI approach drops straight onto any SIP-based PABX.

Direct SIP · zero carrier cost

Transfers into your 3CX & Yeastar with no carrier fees

Linking your 3CX or Yeastar to Tronic AI over direct SIP URI lets the agent connect to your users, IVR, ring groups and queues directly on the PBX — bypassing your provider lines. That means no carrier costs on the calls it transfers across. And because they run on our own network, calls from a Tronic-hosted 3CX or Yeastar to your Tronic AI agents are free — like every Tronic-to-Tronic service call.

Beyond the built-in AI

Link your agent to any CRM or API

You are not boxed in by the limited capabilities of 3CX or Yeastar’s built-in AI. Tronic’s agent connects to your CRM, APIs, webhooks and MCP servers — so it takes real actions and answers from your own data, not just a script.

Any CRM

Sync contacts, log calls, create leads and update records in your CRM as the conversation happens.

Any API or webhook

Book jobs, check availability, take payments or trigger any workflow over webhooks — real actions, not just answers.

Knowledge, RAG & MCP

Connect knowledge bases, RAG and MCP servers so the agent answers from your own data, accurately.
