Connecting the Equipment Configuring Steering Digits and Outbound Call Routes 4 Configuring Steering Digits and Outbound Call Routes The Configure Outbound Call Routes page appears after you click the Next button on the SPA9000 NAT Traversal page. STEP 1 Check one of the Select backup boxes to designate a line to be automatically used by the system in the event that the primary line is not available. STEP 2 In the Prefix field, enter a unique steering digit for each SIP line. • A prefix, or steering digit, is the first number that a user dials before entering the phone number for an external call. • You can use a prefix to determine which line is chosen for a particular type of call. This example uses 8 for Service Provider 1 and 9 for Service Provider 2. These Service Provider fields correspond to Line 1-4 on the Configure SPA9000 Voice Services page. In an earlier example, Line 1 was configured for relatively inexpensive ITSP service, and Line 4 was configured for PSTN access. When a user presses 9, the call is transmitted via the ITSP. • To choose steering digits, you can use any digit that is not the first digit of an extension number. For example, if your extension numbers are 1xx for primary extensions and 2xx for hunt groups, the numbers 3-9 are available for steering digits.
