Calling through DISA
To call an extension
When outside callers access extensions in the PBX, a
prerecorded message greets the caller and gives information
about how to access an extension. You do not need the
operator's assistance.
You may be able to access system features or call an outside
party with your password depending on the security mode.
For more details, refer to the Feature Manual.
