# Overview

> Find the Phonely block that matches your task and see where it can run in a flow.

Blocks are reusable capabilities that handle individual steps in a flow, such as speaking, collecting information, making a decision, sending a request, or processing data. Use this page to compare blocks and see where each can run.

Some blocks also share settings for caller feedback, failure routes, and reporting. See [Common Block Settings](/blocks/common-settings) to configure those options.

<Info>
  The **Available in** column shows where a block can run. **All stages** means pre-call, live call, and post-call. The block picker filters by the flow direction and stage where you open it.
</Info>

Blocks that connect to external services have one canonical guide under [Integrations](/integrations/overview). Each guide covers both connection setup and using the integration in a flow.

Greeting, Start Flow, and Make Call are [flow triggers](/blocks/flow-blocks/start-flow), not reusable blocks. Phonely adds the appropriate trigger when you create a flow.

## Conversation

| Block                                          | Use it to                                                                    | Available in |
| :--------------------------------------------- | :--------------------------------------------------------------------------- | :----------- |
| [Talk](/blocks/flow-blocks/talk)               | Handle a multi-turn conversation, collect information, and branch by outcome | Live call    |
| [Collect](/blocks/conversation-blocks/collect) | Collect specific information from the caller in a structured format          | Live call    |

## Flow control and routing

| Block                                                           | Use it to                                            | Available in        |
| :-------------------------------------------------------------- | :--------------------------------------------------- | :------------------ |
| [Filter](/blocks/flow-control-and-routing/filter)               | Route the flow using available data                  | All stages          |
| [Time Filter](/blocks/flow-control-and-routing/time-filter)     | Route the flow based on a weekly schedule            | Live call           |
| [Transfer Flow](/blocks/flow-control-and-routing/transfer-flow) | Continue the call in another flow for the same agent | Live call           |
| [End Call](/blocks/flow-control-and-routing/end-call)           | End the call with a final message                    | Pre-call, live call |
| [Delay](/blocks/flow-control-and-routing/delay)                 | Wait before running connected post-call blocks       | Post-call           |

Use [Talk exit conditions](/blocks/flow-blocks/talk#exit-conditions) for conversational outcomes and Filter for data-based routing. Transfer Flow stays within the agent, while [Transfer Call](/blocks/communication-blocks/transfer-call) sends the call to a phone destination.

## Calls and messaging

| Block                                                                           | Use it to                                     | Available in         |
| :------------------------------------------------------------------------------ | :-------------------------------------------- | :------------------- |
| [Transfer Call](/blocks/communication-blocks/transfer-call)                     | Transfer a call to one or more phone numbers  | Live call            |
| [Send SMS](/blocks/communication-blocks/send-sms)                               | Send a text message to a phone number         | All stages           |
| [Send Email](/blocks/communication-blocks/send-email)                           | Send an email to one or more recipients       | Live call, post-call |
| [Email & SMS Notification](/blocks/communication-blocks/email-sms-notification) | Send a call summary by email, SMS, or both    | Post-call            |
| [Redial](/blocks/communication-blocks/redial)                                   | Schedule one or more follow-up call attempts  | Post-call            |
| [Campaign](/blocks/communication-blocks/campaign)                               | Queue an outbound call in a selected campaign | Post-call            |

Use Send SMS or Send Email when you control the message content. Use Email & SMS Notification to deliver the conversation summary automatically after the call.

## Data and automation

| Block                                                               | Use it to                                   | Available in           |

| [Send Call Data](/blocks/data-and-automation-blocks/send-call-data) | Send call data to an endpoint               | Post-call              |

## Integrations

Provider-connected blocks and branded webhook automations are documented under [Integrations](/integrations/overview). Use that section to compare their actions and configure accounts, webhooks, inputs, variables, and tests.

<Warning>
  The picker shows where a block can run, but it does not confirm that the block is fully configured. Complete its required settings and resolve any errors in the [Flow Checklist](/workflow-checklist) before publishing.
