Configuring Dial Plans
About Dial Plans
Cisco SPA500 Series and WIP310 IP Phone Administration Guide
When a user lifts a handset or presses a speaker button on the IP phone, 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.
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 web administration user interface 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 SPA9000 system:
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).
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).
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.
