  • No data sent to third parties

Infrastructure

Self-Hosted Push Gateway

The Aria Push Gateway is a lightweight SIP B2BUA that sits between your PBX and mobile devices. It maintains SIP registrations on behalf of phones, intercepts incoming INVITEs, and delivers instant VoIP push notifications. Outgoing calls route through the gateway too.

  • Maintains SIP registrations for mobile devices
  • Delivers APNs (iOS) and FCM (Android) push
  • B2BUA for outgoing call origination
  • REST API for device registration and call signaling
  • SQLite storage, ~256MB RAM, runs anywhere
