I have numerous Cisco ATAs 186 registered on the Callamanger 4.1. Hotdialing is configured with special CSS and Translaton Pattern that converts called number to the contact center number. Calls are routed via CUBE to the CUCM and than to the Genesis contat center.
In general all works fine.
Sometimes, some ATA originates massive outbound calls. That calls are empty calls but creates heavy load to the contact center. In case of more than one attacking ATA load to the contat center increases dramatically.
Is it possible to limit amount of calls originated from ATA? Something like, no more than X calls per minute.
Can broken cradle or on-hook/off-hook mechanism on the analog phone cause this issue?
