I’m building a video doorbell with a door station (video source) that will video call extensions, which are building tenants’ mobile phones. I need to push call notifications to the mobile phones and keep them registered, even if the app is closed, etc.
- Is Asterisk a good solution for the server-side of this?
- How do I keep the phone registered and push call notifications to them?
- Is there multi-tenancy so each building is it’s own mini pbx?
- Is there a hosted solution that does 1-3 and doesn’t include outbound dialing/phone plans?
