Fritzbox callmonitor should be working with internal calls

Hello,

I dont know if this is a bug, a missing feature on AVM side or a missing feature of the component:

It would be great if the fritzbox callmonitor would work with internal calls.

I have a SIP Intercom at my door that works with my Fritzbox over an internal call. I like to monitor this call and trigger a camera snapshot.

Thanks
Jan

It is!
I tried many call monitors for the Fritzbox, but this is not implemented from AVM.
