I have a basic Auto Attentant configured, and when inbound caller selects an option; say 1, they get a "wait while I transfer your call" and then the hold music. This last for 15 seconds or so; then call gets transferred to the correct DN.
Looking for direction to remove the long delay. Assuming this is a UNITY issue and not CM related, as transfer from handset to handset work just fine.
It's CUCM v9.1 and Unity v9.1
