Besides the header (name, input and output-type) a mapping table contains multiple entries. Each entry speci-
fies a specific value of the routing table input-type and a value that shall be applied to the call property specified
with the output-type of the table. When a call arrives a mapping table, the following procedure is applied:
1. Examine the call property as specified with the mapping table input-type.
2. Select the best matching entry. This means that the key of each of the entries is compared to the call prop-
erty and the entry that matches best is chosen.
3. Execute the entry. This means replacing the property specified with the output-type of the mapping table
with the value of the selected entry.
Let's examine the mechanism of mapping tables in more detail.
call that is routed through this mapping table. The call contains various call properties that are examined and
modified by the mapping tables:
Example #1: This example shows a mapping table that selects the best matching entry based on the called party
number of a call and, once found, sets the called party URI. In the example a call arrives to the mapping table
with a called party number of 201. The mapping table selects the first entry, which matches best, and sets the
called party URI of the call to sip:john.smith@nil.net.
