This conversation prompts callers to enter the number that they want to transfer to. In order to protect Cisco Unity from toll fraud and unauthorized use, Cisco Unity performs the transfer only when the Default SystemTransfer restriction table permits it.
This conversation prompts callers to log on to Cisco Unity. After callers enter their Cisco Unity user ID and password, Cisco Unity prompts them to enter the number that they want to transfer to. This is to protect Cisco Unity from toll fraud and unauthorized use. Cisco Unity performs the transfer only when permitted by the transfer restriction table that is associated with the class of service for the subscriber who logged on.
A call that is transferred by an Auto Attendant through a Unity Connection will not get the proper call treatment when the user dials a extension that is using analog phone connected to VG224 and the extension is busy. The message "You cannot be transferred to this number. Check the number and try again" is played instead of a fast busy signal.
This happens when the Cisco Unity Connection does a Caller System Transfer to an extension that is busy and has a busy trigger when the particular directory number is set to 1 on the Callmanager. In this situation, Cisco Unity Connection plays the message: You cannot be transferred to this number. Check the number and try again
As designed, Cisco Unity Connection plays the message You cannot be transferred to this number. Check the number and try again. If the number is correct, the message that plays should be The number is busy please try later (or an equivalent message whenever the number is busy). As a workaround to the above problem follow step below to achieve the desired message.
Make changes in Cisco Unified Communications Manager (CallManager).
Set the Call Forward Busy Internal and External for Analog phone to a dummy extension.
Create a CTI Route point for the dummy extension, and set a call forward all to voice mail for this extension.
Copy the existing default Voice Mail Profile and create a new one with a Voice Mail Box Mask set to above extension.
Apply this profile to the CTI Route Point you created in Step 2.
Make changes in Cisco Unity Connection.
Create a Call handler (for example, Busy-Call-Handler) and record a greeting: The number you are dialing is busy. Please try again later
Send the call to the opening greeting call handler of the voicemail (or hang-up as per your requirement).
Create a forward routing rule, and set the call to route to the Busy-Call-Handler when the forwarding party is the dummy extension.
