AI Agent

Cold Calling Agent

Cold Calling Agent that automates sales workflows using your data and tools.

The challenge

Representatives spend most of the day dialling numbers that never answer, so the long tail of the list is never worked at all. Call quality drifts from the approved script, consent and do-not-call checks depend on someone remembering, and only a tiny sample of calls is ever reviewed for what was actually said.

The outcome

Azure Communication Services places the calls, Azure AI Speech handles the conversation in real time, and a Microsoft Foundry agent runs the approved script grounded in Azure AI Search. Qualified conversations book a meeting; anything complex warm-transfers to a person mid-call. Every call is recorded, scored and consent-checked.

Build This Solution

01 — Architecture

End-to-end architecture

A campaign starts from the CRM lead list, is scheduled and consent-checked, then dialled over Communication Services. Speech turns the conversation into text and back into a natural voice, the Foundry agent runs the script against grounded offer knowledge, and every outcome is written back to the CRM and the campaign dashboards.

02 — Workflow

Process & decision workflow

How a call is targeted, dialled, transcribed, driven by the agent and then branched. Qualified, straightforward conversations book a meeting straight through, while complex, hostile or high-value calls warm-transfer to a human SDR with the full context.

AI responsibility boundaries

The agent identifies itself as an AI at the start of every call, honours do-not-call and consent registers, and stops immediately on request. It does not close contracts, quote unapproved pricing or capture payment details. Hostile, sensitive or high-value conversations warm-transfer to a human SDR with the full transcript, and every call is recorded, scored and auditable.

05 — Personalization

Personalization & evolving process

The same methodology applies to every agent in the catalog. Tune the market, the script, the rules and the value model — the page structure stays identical.

Market & offer profile

Define the target segments, regions, languages, calling windows and regulatory context — consent registers, do-not-call lists and recording disclosure. For outbound sales the personas are the prospect, the SDR, the sales manager and the compliance owner.
