The service receives a request from the ingress gateway for establishing a communication service for the calling party terminal. The service obtains information associated with the calling party terminal, which may be based on the trunk and its relationship to a customer, in which the information is to be used for applying at least one of a routing decision and policy decision to the communication service, and appends a tag to the request based on the information. The service may then transmit the request appended with the information to a routing device, which may then use the information when providing the service. ## Claims ### Claim 1 A differentiated routing system comprising: a computing system in communication with an ingress gateway that provides a communication service for a calling party terminal in a native network domain, the native network domain comprising a plurality of egress gateways that route the communication services to a corresponding plurality of destination network domains, the computing system comprising a processor and a memory to store instructions that are executed by the processor to: receive a request from the ingress gateway for establishing a communication service for the calling party terminal;
