I keep searching for this link to download ODBC drivers on google search but it does not show up. It is buried deep within some Avaya pages. So now I put it here for my ease of use.
ftp://ftp.intersystems.com/pub/cache/odbc/

Also there are some resources that reference the below link for downloading other driver types (eg: JDBC) but the site is a pain to use during the times I have tested.

Avaya Aura Contact Center

If you have access to an Avaya Aura Contact Center installation, you can get JDBC drivers at the below path:
D:\Avaya\Contact Center\Manager Server\iccm\bin
Files: CacheDB.jar, cachejdbc.jar

ODBC Drivers are available on the installer ISO:
<INSTALLER_ROOT>\ThirdPartySoftware\IntersystemsCache\CacheODBCDrivers\
