ABSTRACT:
An MSC receives a request from a mobile station to originate a call to a directory number that corresponds to another mobile station. The MSC sends a query that includes the directory number to an off-board translation center (OTC). The OTC determines from the directory number whether the call can be transcoder-free and, if so, provides a response with a transcoder-free indication. If the response includes a transcoder-free indication, the MSC selects a transcoder-free communication path for the call.
