- The page says pgw holds an incoming INVITE for up to 30 seconds by default while push wakes the app.
Field notes
The described flow starts with RFC 8599 parameters in the client's REGISTER and ends when the app registers again and pgw forwards the held call. The page says the gateway can strip push parameters before the REGISTER reaches the PBX and describes a managed mode for ringing multiple devices. It also lists a static Go binary with SQLite, Prometheus metrics, and health checks.
