Hello.

Last weeks I'm tested lot of integrations and solutions for my outdoor HikVision camera door station. With SIP enabled and Asterisk, without, using two-way audio from Advanced Camera Card/Frigate or acardace/hikvision-doorbell-card. Every solution have smaller or bigger culprits. I decided to do something of my own, everyday I have very small amount time for projects like this, but nowadays we have AI with agents :wink:

This is complete solution to integrate SIP capable door stations into HA. Pieces are:

  • add-on - minimal SIP server acting as RTP-WebRTC bridge with call history, no need Asterisk anymore
  • integration - communicate to add-on and expose all functionalities and doing proxy for WebRTC signaling
  • cards - main card with audio and controls and second for call history

Documentation is still a bit chaotic but I think for people who have had contact with other solutions setup of mine integration won't be a problem for them.

Add-on: hass-addons/sip_indoor_station at master · arturzx/hass-addons · GitHub
Integration: GitHub - arturzx/sip-indoor-station-integration: SIP Indoor Station Home Assistant Integration · GitHub
Cards: GitHub - arturzx/sip-indoor-station-card: SIP Indoor Station Home Assistant Lovelace Card · GitHub

I'm waiting for your tests and feedback :slight_smile:

A simple SIP server solution - that's something new :slight_smile: I'm using the Asterisk add-on/app with SIPcore integration and was also wondering how some things could be done differently. Regarding your solution:

  1. Is there only one explicitly defined SIP user - the one for the intercom?
  2. Can I dial into the intercom, or only receive calls?
  3. What happens to an ongoing call if I close the companion app or refresh the browser? Will the call be interrupted, or will the integration somehow maintain the connection?

  1. Yes - key is simplicity, one station, one user, one connection :wink:
  2. I don't even know if my station supports it and. For now only receiving is possible.
  3. Connection add-on station will last. When you back to card you can continue it or hangup normally, card is stateless. At least that's how it should work, but I haven't checked yet how card will behave in this scenario, I will check it, thanks.
