DS-KB8112-IM API Detect Bell Button Pressed

[burjaminergate]

Hello. Please tell me how in HikVision DS-KB8112-IM programmatically track the click of a call button. I could not find a separate API method.
On request

http://20.xxx.xxx.xxx/ISAPI/System/IO/outputs/1

:

<?xml version="1.0" encoding="UTF-8" ?>
<IOOutputPortversion="2.0"xmlns="http://www.isapi.org/ver20/XMLSchema">
     <id>1</id>
     <name>COM</name>
     <IOUseType>custom</IOUseType>
</IOOutputPort>

An error is displayed on a request for exit status
