Description
Each CO/IP path may be assigned for DISA service, which allows an incoming caller to gain
access to the system resources and/or features. The iPECS will answer the outside call and
provide the user intercom dial tone or route the call based on the VMIM/VSF Auto Attendant
announcement settings where Caller Controlled Routing may be defined. The DISA caller may
then access the desired resource using dial codes.
If an Authorization Code is required for DISA access, when the system answers an incoming DISA
call, DND Warning tone is provided to indicate an Authorization Code must be entered.
