E12W - Auto Hang Up if Input A or B is triggerd?

Have you tried the API call http://<doorphone_IP>/api/call/hangup ?
Also, you should check options inside indoor monitor as from what I recall after you open the door from your monitor, the call should hangup automatically in 2-3 seconds.

THX this could work.

any manual about the API?

The full documentation can be found on the Akuvox Knowledge website.

I'm very interested as well in the API documentation!

Also in relation to prevent or cancel outgoing SIP calls.
In my situation, I have a home server which processes local alerting (chime) when the button is pressed.  As the server has knowledge of presence within the premises, the server could instruct to the door phone to either, not call in the first place or hang up immediately.

that call actually works very well!

Can you also use the /api/call endpoint to call a specific extension ?

This could be a nice solution, to having the doorphone perform no call by default and instruct it to call a specific number if nobody is on site!

I could even include logic as to who should be called based on availability statuses
