By creating a caller group, you can apply one rule to multiple callers without having to recreate the rule several times. Caller groups contain multiple entries from your contacts list and the Cisco Unity Connection directory.
Using groups can help you organize callers in a number of ways. For example, you could create a caller group of your top-priority clients and co-workers. To ensure that these callers can reach you when you are in meetings, you would create a rule set with one rule that transfers calls from anyone in the group to your mobile phone during your meeting times and a second rule that transfers other calls to voicemail.
The following types of callers can be members of caller groups:
| Contacts | Callers who are entered in your contacts list. |
| Administrator-defined contacts | Callers who are in the Connection directory but who are not enabled to use Connection features and do not have a voice mailbox. |
| Connection users | Callers who are in the Connection directory, have a voice mailbox, and are enabled to use Connection features. |
 Note | When a caller group contains a caller who is listed in the Cisco Unity Connection directory and the caller is later removed from the system by your Connection administrator, the caller will also be removed from your caller group. |
