Hi there!
I have been looking around for quite a while now, but did not find a suitable solution to my problem. I have a VOIP/SIP doorbell, wich starts a “broadcast”-call to all phones in the house. This system is based on the AVM Fritz!Box, wich has a nice call monitor, but due to technical restrictions, the call monitor does not recognise those boradcasts.
So my intention is to have a kind of voip client, that registers to my Fritz!Boxes VOIP server and listens for incoming calls. If the caller id is a special one (in my case “TORKLINGEL”), an automation shall be triggered.
Searching the web an this forum, I did find integrations beeing able to make a phone call. But none seem to be able to receive those.
Did I miss something or do you have any other suggestions? My HA runs inside an unofficial docker on a debian based machine (quite beefy home made NAS).
Best
Pascal
