Hopefully I'm not missing the obvious but anyone know how to disable the waiting for line beep or make an ARS failover happen instantly? I have IP Office (Powered By) 11.0.0.1 with SIP lines. Certain numbers are not routable by the main SIP provider so there is a backup ARS that points calls to a secondary provider--however the customer has to hear a very loud beeping in their ear for a few seconds before those calls go through. Thanks for the help!
