1. The phone begins collecting the dialed digits. The inter-digit timers starts
tracking the time that elapses between digits.
2. If the inter-digit timer value is reached, or if another terminating event occurs, the
phone compares the dialed digits with the IP phone's dial plan. (This dial plan is
configured in the configuration utility in the Voice tab, on the tab for each
extension (Ext N), under the Dial Plan section.)
If the phone is part of a Cisco SPA 9000 system:
3. If the phone dial plan allows the call to process, the dialed numbers are sent to
the Cisco SPA 9000.
4. The Cisco SPA 9000 compares the dialed digits to the CALL ROUTING RULE (on
the SPA 9000 Voice > SIP page, PBX Parameters section).
5. If the call routing rule allows the call to process, then the Cisco SPA 9000
compares the dialed digits to the LINE INTERFACE dial plan (on the Cisco SPA
9000 Voice > Line N page, Dial Plan section).
6. The Cisco SPA 9000 uses the information in the line dial plan to manipulate the
number (for example, to remove steering digits) and then transmits the number.
The dial plan feature (digit sequences and timers) is not used with the Cisco
SPA525G2 phone line associated to Mobile Link (a Bluetooth-enabled mobile
phone). Mobile phone dial plan rules continue to apply in this scenario.

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.
White space is ignored, but may be used for readability.
