Call Forward No Answer
Call Forward No Answer and Second Level Forward No Answer forwards
an unanswered call to a Call Forward No Answer Directory Number (DN)
after a predetermined number of rings. This feature is enabled at the TSP
level when defining the ISDN BRI DN. Both the external and internal Call
Forward No Answer features are configured at the DSL level using LD 27.
The call can be specified to be forwarded to the attendant, to an assigned
hunting DN, or to a flexible Call Forward No Answer DN by using LD 15.
When a call originated by an ISDN BRI terminal is forwarded to a
predetermined DN specified in LD 15, the display on that ISDN BRI terminal
is not updated to indicate a call modification.
