We have a CUCMBE deployment with UC and Unity Connection 7.1 (3). All inbound calls are forwarded directly to VM where a call handler references a business hours/after hours calendar. Between 7:45 AM and 5 PM, all calls are immediately transferred back to an extension in UC that serves as a hunt pilot. After business hours, calls immediately are diverted to the main number voicemail box. All of this works exactly as planned. The issue is that at the time of transfer two beeps are played. Since the transfer happens immediately during business hours, callers are greeted with the double beep and then they hear ringback as the call cycles through the hunt group. Since we only recently switched to this system, this double beep is a new phenomenon for the incoming callers and there have been numerous complaints. When calling after hours, the callers immediately go to voicemail with any beeps or even a ringback. This is fine and seems to indicate that the double beep is related to the transfer.
Is it possible, without using ToD routing in UC, to remove this double beep on transfer while maintaining the call handler functionality in Unity Connection? As others have pointed out, the call handler method allows for use of the calendar and makes it easy enough that people can be trained to update the schedule. We have used both Supervised Transfer and Release to Switch with the same double beep result. I have checked through all of the parameters I could find in both Unity Connection and UC Manager. I have even heard a transfer to a second call handler as a potential solution but ultimately I need to forward back to the hunt pilot so I am not sure how this would resolve it or even how to configure it.
I appreciate any assistance with this issue as it is not mission-critical but definitely something we would like to resolve.
