How Call Forwarding and Extension Hunting Interact with DID Calls
The following chart summarizes how the system handles unanswered DID calls when Call Forwarding and/
or Extension Hunting are enabled at an extension. For the specific routing details, see:
❥ DID Call Handling with Call Forwarding and Extension Hunting (page 103).
❥ DID Station Intercept and Line Overflow (page 105).
Call Forwarding

Hunting
DID Station
Intercept
Line Overflow
Priority 1
Priority 2
Priority 3
Priority 4
If the call is unanswered, the system checks the highest
priority routing choice first (i.e., Call Forwarding).
If the highest priority routing choice is not set up to handle
the call condition, the system checks the next lower choice.
For example, if an extension has Ring No Answer Forward-
ing enabled and the call routes to that extension while it is
busy, the system will then check Extension Hunting.
If Extension Hunting is disabled or not set up to handle the
call condition, the system checks DID Station Intercept.
If no there routing choices are found, the call will follow
Line Overflow.
Key Ring
Priority 5
If Line Overflow is disabled, the call will go to Key Ring
(with no overflow).
