# Configure Auto-Answer for Calls on Door Phones

Auto-answer feature enables Akuvox door phones to pick up calls automatically. This feature saves time when users have to handle a large volume of calls.

All Akuvox door phones support this feature. This article takes R29 as an example.

## Enable Auto-Answer for SIP Calls

Before using auto-answer for SIP calls, make sure the device's SIP account is registered.

1. Use the device IP to log into its web interface with the username and password. The default is admin.
2. Go to **Account > Advanced > Call** interface. Enable **Auto Answer.**

1. Use the device IP to log into its web interface with the username and password. The default is admin.
2. Go to **Account > Advanced > Call** interface. Enable **Auto Answer**.

## Optional Configuration

You can configure auto-answer delay time and mode by navigating to **Intercom > Call Feature > Auto Answer** interface.

- **Auto Answer Delay** determines how many seconds it will take the door phone to answer the call. If you set it to 3, the door phone will answer the call after 3 seconds.
- **Mode** determines whether the calling party receives the audio or video stream.
