Home Assistant SIP Gateway

Hello,

First of all, I have to say that I’m a complete beginner with Home Assistant (HA). I’ve only worked with ioBroker so far and now I want to learn HA, but unfortunately, quite a few things are completely different.

My first project is:

My doorbell uses SIP and currently rings a Grandstream VoIP phone as the indoor device.

I want to change this so that HA-SIP is called, and the camera image appears on a tablet, allowing me to open the door (via DTMF) with a button.

It would be fantastic if I could also communicate with the doorbell from the tablet using the microphone and speaker.

What I already have is that HA-SIP is registered in my Fritz!Box and can be called with an internal number. That works fine.

However, I’m stuck now, which is also due to my lack of knowledge about HA.

I would like to create an automation that, when HA-SIP receives an incoming call, a different dashboard is opened via Fully Kiosk. Calling the URL isn’t a problem, but I need to set a trigger under Automation, and HA-SIP isn’t in my trigger selection list.

How and where do I do that?

Do I need to write the “incoming call” action as a script under Scripts, referencing a unique ID from a webhook?
And can I then use this webhook ID as a trigger?

Or how do I handle the incoming call?
The call doesn’t need to be answered for the URL request.

To open the door, I would then create a button in the dashboard that, when clicked, makes an outgoing call and sends the DTMF code to open the door.

I don’t think communication between the tablet and the doorbell is possible, if I’m interpreting the issue correctly: Is It Possible to Use Microphone and Speaker for Real-Time Voice Calls via SIP?

Perhaps someone can help me, and please bear in mind that I’m not yet 100% sure where to put each YAML script.

Thank you in advance.

Thank you, this is great. I tried it a few months back and it always stayed quiet on the line. Did you try to receive a call and react to it?

EDIT: I tried it with your options: >-
–ice disabled --use-stun-for-sip disabled --use-stun-for-media disabled
–use-sip-outbound enabled

And receiving calls works!

EDIT2: Actually the magic switch for me is only this:

global_options: “–tcp off”

All other options are empty/default. That way I can receive and place calls just fine.
