66 CHAPTER 3: CONFIGURING VCX USERS AND SERVICES
Your VCX system includes several preconfigured Classes of Service. You
can modify an existing CoS or create a new one. In addition, you can
create CoS elements and add them to an existing CoS, or you can modify
existing CoS elements.
Note the following additional CoS considerations:
Emergency calls (such as calls to 911) are not subject to CoS
restrictions
and cannot be blacklisted. Emergency numbers are
configured and controlled through the Emergency Services menu
option (see Configuring Emergency Services
).
System-wide Speed Dial numbers are subject to Class of Service
restrictions. For example, if a phone is assigned to a CoS that prohibits
dialing toll-free numbers, a System Speed Dial configured for a specific
toll number will not work on that phone.
When you create a new phone profile (see Managing Phone
Extensions), the system assigns the default CoS unless you specify a
different one. If you edit the properties of the default CoS, verify that
it contains a minimum set of permissions.
