Mapping tables are identified by a name (string) and referencedin the routing tables for execution. Like the routing table, a mapping table finds the best matching entry andexecutes it; but unlike the routing table, the execution means manipulating a call property. Thus a mappingtable always examines one call property (the input-type) and changes another property (the output-type). Asfor the routing tables the call router provides a number of different mapping table types. A mapping table lookslike the following:Figure 60. Mapping table outlineEach table contains a header and one or more entries. The header declares the input and output-type of themapping table as well as its name.Unlike a routing table, a call property pair characterizes a mapping table, the input and output-type. While theinput-type defines which call property is examined by the call router, the output-type defines which property ismodified once the best matching entry is found, for example, you may want to find a best matching entry in amapping table based on the presentation indicator and, once found, you want to manipulate the calling partynumber of the call. In this case you chose an input-type of calling-pi and an output-type of calling-e164There are three different kinds of call properties, calling party properties, called party properties and genericproperties. When a call setup is to be routed by the call router, most properties appear as calling and as calledparty properties, for example, you have a calling party number and a called party number to examine. Thereare other properties (e.g. the information transfer capability), which is a property of the whole call and not ofeither party.Step Command Purpose1node(ctx-cs)[switch]#no routing-tabletable-nameDelete the routing tabletable-name.Note: You do not have to enter the type of the table whenjust deleting it.
