Origination and Destination Based Routing

Abstract

One or more aspects of the disclosure relate to various functions and processes related to routing of calls based on origination and/or destination information. In one aspect, a method may comprise receiving a request for a call session, and the request may include an indicator that may indicate whether to route a call based on origination and/or destination information of the call session. Based on the indicator, a routing element may determine whether the call session should be routed based on origination information and/or destination information.
