Changing Call Commands
To change the command for a supplementary service (for example, to change *69 to *100), change the
context identifiers in the Call Command field on the Web configuration page. For more information, see
Chapter 6, “Call Commands.”
Note You cannot change supplementary services by means of the voice configuration menu.
Cancelling a Supplementary Service
You can deactivate some supplementary services by pressing *70 before making a call. You can also
configure your system to have services disabled by default and enabled on a call-by-call basis. Use the
32-bit Call Features plan to handle your services in this manner. For more information, see the
“CallFeatures” section on page 5-23.
Common Supplementary Services
The supplementary services described in this section, and their configuration and implementation,
depend on the system of the country in which the service is activated. For information about your
country’s implementation of services, contact your local Cisco equipment provider.
