 
Avaya ECS PIM Failure. The ECS PIM stops functioning when the 
AES link on the Avaya switch sends a “Busyout” command. 
 
VDN Return Destination. 
 
The Return Destination VDN feature does not support the call 
conference
 before agent drops the call (expecting return 
destination to set in). That is, the PG will lose track of the VDN 
to which the call was originally delivered and call variables are 
not retained post Return Destination. However, this feature 
supports call transfer before agent drops the call (expecting 
return destination to set in). That is, the PG will keep track of the 
VDN to which the call was originally delivered and call variables 
are retained post return destination. 
 
Return destination cannot be executed multiple times. That is, 
Return Destination can occur only once for a call in Avaya. 
See sections 
 for 
configuring the Return Destination VDN on Avaya and Unified ICM 
respectively. 
2.13.  Multiple PGs 
The Avaya ACD allows connections from multiple PGs. However, while 
using such a configuration, the resources (like Stations, Agents, VDNs, Splits 
and any other resources) used by each PG should be maintained as separate 
configurations.  
Multiple PG deployment on a single ACD can be used to split the load on the 
PG or have a dedicated PG to service a business line in the contact center. 
To deploy multiple PGs on a single ACD, you need to have distinct 
configuration between the PGs. Section 
 describes the configuration of 
two PGs on a single ACD. You can follow the same steps to to configure 
multiple PGs to the same ACD. 
Note: Please contact the ACD vendor for ACD-related issues or limitations on 
connecting multiple PGs to a single ACD. 
2.13.1.  Dual PG Setup  
Note: Ensure that you adhere to the requirements provided in this section 
while deploying multiple PGs. The performance and functionality of the PG 
will be impacted if you do not follow the requirements listed in this section. 
When two PGs are deployed, ICM routing effectively “sees” the Avaya 
system as two independent peripherals. As such, there are some specific 
configuration and operational requirements that need to be put in place. The 
following figure describes the overview of Dual PG setup.
