Notification from VOIP Phone

Hello! We use Yealink T22 VOIP phones and they have a feature where a notification can be sent out when a call is terminated. My goal is to have KM somehow receive this notification, and then update my slack status accordingly. I have the updating slack status (via AppleScript) figured out thanks to this, but I'm not sure how to get the notification from the phone.

The format of the termination notification URL is:

http://[IP address]:15080/callterminated/yealink?device=$mac&local=$local

I found some information about these action URLs here, but I'm not sure what to make of it.

Is there any way to receive this notification in KM to trigger a macro?

Thank you in advance!
