Additional Gateway Files
For ISN Comprehensive and ISN Advanced Speech, depending on the ISN configuration being used, it
may be necessary to copy files from your ISN Application Server machine to the gateway(s). Use the
following table to determine which files need to be copied. Examine the first three columns for the
combination of features that you are using in your ISN. Copy all files from the folder specified in the
fourth column from your ISN Application Server machine to flash memory on your gateways. Refer to
the “copy” CLI command in the gateway documentation for instructions on how to copy files to your
gateways. Typically, you would first copy these files to a tftp or ftp server, then login to the gateways
and copy the files from the tftp or ftp server. IMPORTANT: DO NOT rename the destination files on the
gateway when copying.

What the columns below mean:
Voice Browser: You use an ISN Voice Browser when the ISN is used to queue calls or provide call
transfer after an agent has answered the call.

CSS: A CSS can be used to provide enhanced failover and load-balancing capabilities between the Voice
Gateways and the ASR/TTS servers, HTTP media servers, and ISN application servers. Note that when
a CSS is used, it must be used for ALL of the afore-mentioned servers. You cannot, for example, use it
for ASR servers but not ISN servers.

Call Restart: The Call Restart feature will restart the call in the event of an ISN application server
failure mid-call. The restarted call will appear to the ICM as just another new call. Note that the Call
Restart feature can only be used when the ISN is a type 5 or type 6 VRU or when the ISN is the main
routing client for the call. In configurations where a call is pre-routed by a NIC to an ISN (ISN is a type
2, 3, 7 or 8 VRU), the restart feature can not be used.

Configuring HSRP for ISN
Depending on the registration interval configured in the gateways and Call Manager, there may be a
period ranging from 30 seconds to a few minutes immediately after Gatekeeper failure (when using
HSRP) where you cannot transfer calls to the desired endpoint and callers lose connectivity.

You should follow these configuration steps below to ensure that this does not happen. The configuration
specified below provides seamless HSRP failover behavior.
