Started By
Gateway is spawned by tboamapp.
Role
Gateway Application is used to bridge 2 call legs, according to a set of routes. The Gateway Application receives incoming calls from toolpack_engine, tries to find a matching route, remaps call parameters if required, and then tells toolpack_engine to generate an outgoing call.
It is responsible for:
- Handling call flow
- Accepting / rejecting call legs.
- Routing call legs to the destination naps, according to routing scheme.
- Sending / writing CDR information.
- Starting play / relay stream for early media.
- Remapping call parameters when required
High Availability
Gateway is a Active/Standby type of application. The first instance of the Gateway application to be detected by the toolpack_engine will become active and will be the only instance to take action in the system. In the eventuality where the active instance is unavailable the slave instance will become active. Since there is no preferred instances, the Gateway application don't fall back to the primary host.
Resynchronization
When becoming active, the Gateway instance retrieves all the active calls from Toolpack_engine. The transient calls will be released by the Toolpack_engine.
