We have a Periphonics IVR supporting many different customer apps. Because we do not partition or dedicate ports to specific apps we use a DNISDriver app to link to the app that matches the DNIS. We are experiencing an issue where random calls are getting the wrong app. Specifically, one app that is taking incredibly heavy traffic to the tune of over 1000 a day. Is it possible that cacheing is happening or something to that tune? Has anyone ever experienced this ? It is driving me crazy and Nortel cannot determine if it is a legitimate issue as it is random.
