A campaign dials an audience for you. You upload a contact list, map personalization variables, set a schedule, and the campaign works through the list automatically — with retries, concurrency control, and live progress tracking. Open **Deploy → Campaigns**. > **Info** > > **Outbound vs. inbound.** Campaigns are for **outbound** calling — your agent dials the audience (like appointment reminders or lead follow-ups). To answer **incoming** calls instead, use [Inbounds](/voice-agents/deploy/inbounds). They're separate flows: a campaign needs a contact list and a schedule, while an inbound deployment just routes incoming numbers to an agent. ## Before you start #### Set up telephony Add a [telephony connection](/voice-agents/deploy/telephony) and, ideally, a [group](/voice-agents/deploy/telephony/groups) so the campaign can rotate across numbers. #### Prepare a contact list A CSV with one contact per row — phone numbers plus any personalization fields your agent needs (name, account number, appointment date, and so on). #### Have a configured agent Your agent must be configured and committed before you can schedule a campaign. > **Note** > > By default you can have **10 concurrent agent campaigns**. Concurrent means campaigns that are **Active** or **Scheduled**. The limit is checked when you **create** an agent campaign and when you **pause** an agent campaign. [Contact the Sarvam team](https://www.sarvam.ai/contact-us) if you need a higher limit. ## The Campaigns page The Campaigns page is your home base for outbound calling. When you open **Deploy → Campaigns**, the top of the page shows a **Calls / Concurrency** graph for the last 24 hours. Toggle between the two views and change the window with **1h**, **12h**, or **24h**: * **Calls** — the total number of calls placed across your campaigns over the period. * **Concurrency** — how many calls ran simultaneously, with the **peak concurrency** called out above the chart. Below the graph, your campaigns are split across two tabs: * **Active campaigns** — everything currently running, paused, or scheduled. If you have no active campaigns, the page opens on **Past campaigns** instead. * **Past campaigns** — campaigns that have ended or been cancelled. Each row in either tab shows the same columns: | Column | Description | | -------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Name** | The campaign name you set when creating it. | | **Agent type** | The agent (or workflow) the campaign runs. | | **Status** | The current [lifecycle state](/voice-agents/deploy/campaigns/campaign-lifecycle) — `Active`, `Paused`, or `Scheduled` on the Active tab; `Ended` or `Cancelled` on the Past tab. | | **When** | When the campaign was launched. | Use the search box to find a campaign by name, and the two dropdowns to filter by **status** and by **time** — **All time**, **This week**, **This month**, or a custom **date range**. ## What you can do from here From the Campaigns page you take one of two actions — **create a new campaign**, or **open an existing one to view its details**. The **DND list** button (top-right) opens your org-wide suppression list, which applies across every campaign. #### [Create a campaign](/voice-agents/deploy/campaigns/create-campaign) Launch a new outbound campaign with the four-step wizard. #### [Campaign details](/voice-agents/deploy/campaigns/campaign-details) Open a launched campaign to track metrics, cohorts, and schedules. #### [Cohorts](/voice-agents/deploy/campaigns/cohorts) Understand the contact batches that make up a campaign's audience. #### [Dialing rate & concurrency](/voice-agents/deploy/campaigns/dialing-rate) How attempts per second (CPS) and concurrency shape a campaign. #### [Campaign lifecycle](/voice-agents/deploy/campaigns/campaign-lifecycle) States and actions — pause, edit, resume, and cancel. #### [Do Not Disturb (DND)](/voice-agents/deploy/campaigns/dnd) The org-wide suppression list applied to every campaign. #### [Best practices](/voice-agents/deploy/campaigns/best-practices) How to launch safely and protect your number health. ## Webhooks A campaign can POST an event to your server as each call finishes — with the outcome, transcript, duration, and the agent variables collected during the call. Set the **Webhook URL** in the campaign wizard's **Advanced** step (see [Create a campaign](/voice-agents/deploy/campaigns/create-campaign)). * **Payload** — see the [Campaigns webhook payload](/voice-agents/api/campaigns/webhooks/webhook-payload) reference for every field, including `start_datetime`/`end_datetime` and `output_agent_variables`. * **Delivery records** — every POST attempt is recorded with a status (`running`, `completed`, or `failed`). List them with [List webhook deliveries](/voice-agents/api/campaigns/webhooks/list), filtered by status and time window. * **Retries** — if your endpoint was down, re-deliver up to 200 attempts per request with [Retry webhook deliveries](/voice-agents/api/campaigns/webhooks/retry). > **Note** > > Webhook events fire per call attempt, whether or not the call connected — so you can track failures too. To fetch caller context *before* an inbound call begins, use an [on-start hook](/voice-agents/build/on-start-on-end-hooks) on the inbound side instead. ## Where to go next #### [Inbounds](/voice-agents/deploy/inbounds) Route incoming calls to an agent. #### [Phone Numbers](/voice-agents/deploy/telephony) Set up connections, rent numbers, and create groups. #### [Agent Analytics](/voice-agents/monitor/agent-analytics) Monitor campaign performance — connect rates, engagement, and call logs. #### [Voicemail detection](/voice-agents/build/conversation-settings) Configure what happens when a voicemail box answers.
