4.1.  Route Request 
To initiate a post-route, the Avaya vector that is handling the incoming call must 
include an “adjunct route request” step with the correct ASAI/CTI extension 
specified. 
A “wait” time should be specified after the adjunct route request to allow for 
Unified ICM software to route the call. Although Unified ICM post-route 
destination decision is virtually instantaneous, a typical wait time of four to six 
seconds in the vector is appropriate. The wait time may need to be adjusted 
depending on anticipated call volumes. 
Vector writers should consider what should happen to the call if the Avaya 
cannot properly route the post-routed call, or if the CTI link is down. For 
example, if the label (call destination) returned from the CallRouter is not valid 
(e.g., incorrect Trunk Access Code, extension destination is busied-out, Class of 
Restriction (COR) does not allow the call to complete), you should consider 
how you want the call handled. 
4.1.1.  Route Request Elements 
The Avaya sends a route request to the PG containing the following Route 
Request Elements. 
 
Calling number (CLID)  
 
Called number (typically the VDN)  
 
User-user information  (32 bytes maximum, where the data type is (a) user 
defined or (b) ASCII) 
 
Last set of Avaya collected digits  (CED) (if any) 
 
Digit collection timeout (seconds) 
 
Call priority level (values:  not_used, not_in_queue, low, medium, high, 
top) 
 
Interflow type  (that is., cause of interflow; values: all, threshold, vector) 
 
Time (time the routed call is to spend in the queue before interflow) 
 
DNIS chars  (optional) 
 
Call ID  
 
Trunk group number and trunk number (optional; mutually exclusive with 
calling number) 
 
II-digits 
4.1.2.  Route Request Peripheral Variable Usage 
If the Route Request Peripheral Variable is allowed, the PG will map the Route 
Request elements (such as CLID and Called Number) into Peripheral Variables. 
Unified ICM script writer can then use the information in the Peripheral 
Variables to create scripts that determine which destination best suits the caller’s 
needs. All Peripheral Variable data types are ASCII.
