How the Dialed Digits are Processed

When a user lifts a handset or presses a speaker button, the following sequence of events
begins:
1. The phone begins collecting the dialed digits. The inter-digit timers starts tracking the time
that elapses between digits. For more information, see
on page 59.
2. If the inter-digit timer value is reached, or if another terminating event occurs, the phone
compares the dialed digits with the PHONE (SYSTEM) dial plan (on the SPA9xx Telephone
Configuration > Ext N page, Dial Plan section). For more information, see
Transmission the Dialed Digits, " on page
"Entering a Phone Dial Plan, " on page
NOTE: If a call is placed from a phone that is connected to a SPA9000 FXS port, the FXS port
dial plan applies. See
page 48.
3. If the phone dial plan allows the call to process, the dialed numbers are sent to the SPA9000.
4. The SPA9000 compares the dialed digits to the CALL ROUTING RULE (on the SPA9000 Voice >
SIP page, PBX Parameters section). For more information, see
Rule, " on page 63.
5. If the call routing rule allows the call to process, then the SPA9000 compares the dialed
digits to the LINE INTERFACE dial plan (on the SPA9000 Voice > Line N page, Dial Plan
section). For more information, see
6. The SPA9000 uses the information in the line dial plan to manipulate the number (for
example, to remove steering digits) and then transmits the number.

Digit Sequences

A dial plan contains a series of digit sequences, separated by the | character. The entire
collection of sequences is enclosed within parentheses. Each digit sequence within the dial
plan consists of a series of elements, which are individually matched to the keys that the user
presses. The sequence can include the elements that are listed in
White space is ignored, but may be used for readability.
