Destination groups contain multiple destinations arranged in a sequence and stored under a single group name.
For example, to ensure that you receive calls from a specific contact, you might create a destination group with your primary extension, mobile, and home phone numbers, then create a rule that tells Cisco Unity Connection to transfer calls from the contact to the destination group. To be used in a rule, a destination group must contain at least one phone destination.
When a call is transferred to a destination group, Connection tries the destinations in the order listed until a phone is answered, until the caller leaves a voice message or hangs up, or until the last destination in the group is reached. If the group contains an SMS or SMTP destination, Connection sends the device a text message about the call.
If a destination is not answered, Connection prompts the caller to press 1 to continue waiting while it tries the next destination or to press 2 to leave a voice message. Connection waits for a phone to be answered based on the specified number of rings, which is set in the Rings to Wait field when you create a destination. If you do not specify a number of rings, Connection uses the default value of four rings. You can change the Rings to Wait setting anytime after you create a destination.
When Connection runs out of destinations, the call is forwarded to your default phone number or to the primary extension in the destination group, which is typically your primary extension.
