Alias manipulation is performed immediately when a message such as an ARQ, LRQ, or a Setup is received. Any matching pattern is replaced with the specified string, allowing you to replace characters or strings that are hard or impossible to dial on certain endpoints. Normal call lookup is performed following alias manipulation.
