# Configure Sequence Call

When users initiate a sequence call on the door phone, the target numbers will be called in order until someone answers. This feature is useful when the homeowner is unavailable, as it can forward the call to another family member.

## Configure Local Sequence Call

### S532, X912, X910, R28, R27, R20 Series, R25 Series, E12, E13, E21 and DB01

E21 should be the firmware version 321.30.10.10 or higher.

We take R20K with version 320.30.11.21 as an example.

1. Log in to the device’s web interface with the username and password. The default is admin.
2. Navigate to the web **Intercom > Basic > Manager Dial** interface.
3. Select **Sequence Call** and set the timeout value. This determines how long to wait before calling the next number if the previous call is not answered.
4. Enter the target IP/SIP numbers, one in each box.

When visitors press the push button or the manager button on the door phone, calls will be made in order.

### S539, S538, S535, X916, X915, R29, E18, and E16

We take R29 with version 29.30.10.343 as an example.

1. Log in to the device’s web interface with the username and password. The default is admin.
2. Navigate to the **Directory > Directory Setting** interface.
3. Select the desired contact and assign it to the self-created group.
4. Select Firstly, Secondly, or Thirdly from **Priority of Call**. If Firstly is selected, the contact will be called prior to other contacts when a group call is made.

When users initiate the group call on the door phone, contacts in the group will be called in sequence.

## Configure SmartPlus Cloud Sequence Call

When the door phone is connected to the SmartPlus Cloud, the sequence call feature will be enabled automatically.

You can decide what the device will do when the call is refused, and users can configure the call numbers on the SmartPlus App.

### On the Door Phone’s Web Interface

You can decide whether the door phone will call the next number when the sequence call is refused.

1. Log in to the device’s web interface with the username and password. The default is admin.
2. Navigate to the **Intercom > Basic > Sequence Call** interface. Select the desired option.

- Call Next: The device will continue to call the next number.
- Do Not Call Next: The device will stop calling.
