# AI Sales Dialer overview

> What the AI Sales Dialer is, sequential vs. parallel mode, and how it differs from Power Dialer, AI Sales Dialer Legacy, and Smart Dialer.

<Note>
  Learn what the AI Sales Dialer is, how sequential and parallel mode differ, and how to tell which dialer your account is using.
</Note>

**User level**: Admin, Agent, Supervisor

***

The AI Sales Dialer is CloudTalk's outbound calling engine for running high-volume call campaigns. You build an audience, the dialer works through it for your agents, and every call is captured with an outcome so you always know where a campaign stands.

  The two dialing modes
</h2>

You choose the mode per campaign when you set it up.

* **Sequential mode (1 line).** The dialer serves one contact at a time. Your agent reviews the contact, places the call, talks, and sets an outcome before moving to the next. Best for considered, higher-value conversations where preparation matters. See [Sequential mode (1 line)](/en/articles/17025671-sequential-mode-1-line).

- **Parallel mode (2+ lines).** The dialer calls several contacts at once (up to 5 lines) and connects your agent to whoever answers first, dropping the rest. Best for maximizing talk time on large lists. Parallel mode is a paid add-on and each agent using it needs a Parallel Calling seat. See [Parallel mode (2+ lines)](/en/articles/17025675-parallel-mode-2-lines).

  Which dialer am I using?
</h2>

| **You see** | **What it is** | **Status** |
| - | - | - |
| **AI Sales Dialer** | The current product. Sequential and parallel campaign dialing. | Current |
| **AI Sales Dialer Legacy** | The previous version of the AI Sales Dialer. Being phased out. | Legacy |
| **Power Dialer Legacy** | An older campaign dialer. No longer receiving new features. | Legacy |
| **Smart Dialer** | A separate click-to-call tool that dials numbers you collect from a web page or CRM. Not a campaign dialer. | Separate feature |

In the CloudTalk Phone app under **Campaign dialers**, you'll see a **Dialer** button. Clicking it shows two options:

* **Dialer** ("What you use today"): the legacy AI Sales Dialer

* **Dialer** with a **New** badge ("Try the new dialer"): the new AI Sales Dialer described in these articles

If you see separate **Power Dialer** and **Smart Dialer** buttons instead, you're on the older legacy products.

  What makes the AI Sales Dialer different
</h2>

Compared to the Power Dialer and the previous AI Sales Dialer, the new version brings:

* Faster, more reliable contact queueing that never serves the same contact to two agents

* Multi-number contacts: the dialer can try more than one number per contact

* A dedicated statistics view with disposition breakdown, conversion tracking, and exports

* Dispositions that are CloudTalk tags, so outcomes flow straight into your reports and CRM

* Voicemail drop, scheduled callbacks, warm transfer, and contact prioritization built in

* Fresh contact prioritization: choose whether to dial new contacts before retrying earlier no-answers

* Tag and CRM list prioritization: rank audience segments so higher-value groups dial first

  Key concepts at a glance
</h2>

* **Campaign.** A list of contacts plus the rules for how your team calls them. You create campaigns in the Dashboard.

- **Disposition.** How an agent records what happened on a call ("Interested," "Not interested," "Wrong number," etc.). Dispositions are required before moving to the next contact, so no call goes unrecorded.

* **Contact queue.** When an agent starts a session, the dialer reserves a batch of contacts for them and serves them one by one (sequential) or in groups (parallel). Admins set the batch size per campaign with **Session lock size** (15 by default). The queue refills automatically as contacts are worked.

- **Session.** An agent's active dialing window on a campaign. Start a session to begin calling; pause or end it when you're done.
