Configuring Dial Plans
Dial plans determine how the digits are interpreted and transmitted. They also
determine whether the dialed number is accepted or rejected. You can use a dial
plan to facilitate dialing or to block certain types of calls such as long distance or
international.
If the Cisco SPA500 Series and WIP310 IP Phones are part of the Cisco SPA9000
Voice System, dial plans are configured on the Cisco SPA9000. In installations
where a Cisco SPA9000 is not present (such as IP Centrex installations),
installations where the phones are removed from the SPA9000 (such as by a VPN),
or other situations, dial plans can be configured on the IP phone using the web
administration user interface.
For more information on using dial plans on the Cisco SPA9000 Voice System, see
the
Cisco SPA9000 Voice System Administration Guide
. See the
Appendix C,
“Where to Go From Here,”
for the location of the document.
This section includes information that you need to understand dial plans, as well as
procedures for configuring your own dial plans. This section includes the following

same manner.
