Explanation
In Cisco Expressway, search rules are the dial plan mechanism that can be conditioned on both the protocol (SIP or H.323) and the source zone of the call. Each search rule has criteria fields including 'Source' (which zone the call originates from) and protocol matching, allowing administrators to define different routing behavior based on how and where a call originates. Presearch transforms modify aliases before search rules are evaluated. Call policy controls whether calls are allowed or rejected. Policy services are external policy servers. Only search rules offer the combination of protocol-based and source-based routing differentiation described.
