Endpoints
An endpoint represents a device that can receive voice calls. It may be an external SIP device, such as an Asterisk server or SIP PBX, or a hosted application that CarrierX runs.
New partners are provided a system_gateway endpoint, which cannot be modified. This endpoint is a logical representation of the CarrierX switches, and determines the IP addresses where traffic is sent and received.
In call detail records, a call coming into the PSTN would designate the system_gateway endpoint as the inbound leg. The endpoint being routed to would be listed as the outbound leg. Alternatively, for inbound calls sent to a third-party endpoint, users will need their switch to accept traffic from any of the IPs listed in the system_gateway endpoint.
