Outbound call routing 29-9
Chapter 29: Understanding Wave Call Routing
Wave Global Administrator Guide
The above figure shows the path by which a call is sent through Wave using automatic route
selection. After determining that the call is an external call (based on the first digit collected),
Wave looks up the routing type configured in the First Digit Table. In order to process a call
using automatic route selection, the routing type must be
Outbound Routing. Then the call is
passed to the Automatic Route Selection process (detailed in on page 29-11, and contained in
the dashed line).
Special Digits Table
The Automatic Route Selection process first compares the dialed digits to the numbers in the
Special Digits Table, which lists numbers that every phone in Wave is permitted to call (such as
911). In the Special Digits Table, numbers can be blocked, redirected to an internal destination,
or routed to an outbound routing table. If a number does not have a match in the Special Digits
Table, Wave determines the call type, and sends the call to the next appropriate routing step.
For example, if the number 555-1212 is dialed, it would find no match in the Special Digits
Table on page 29-11. Since this is a 7-digit number, Wave uses the North American Numbering
Plan to determine that this is a local call, and sends the call to the next step in the process.
Home area code
When 7-digit numbers are sent to the automatic route selection process, Wave looks up the home
area code and sends this information along with the dialed number to the global area code table
for further routing attempts.
In our example, Wave looks up the home area code (408), and sends this information along with
the dialed number to the next step in the process.
