What i want to know if when a subscriber goes on vacations there is any way to delegate is voice mail's to any other subscriber without sharing is password. That is an issue because subscribers aren't able to change there voice mail greeting so they could announce that they are on vacations.
You really only have two choices here that I can think of (without sharing the Password)
You can change Unity 5.x to use the "Last Redirecting Number" on a Call Forward and have your user Forward to another person who is covering for them while they are away. This way the Messages will be left in the "covering" persons mailbox.
Enable your users to record the "Alternate greeting" during a leave of absence.
You can customize how Cisco Unity handles calls to subscribers who have the alternate greeting enabled. For example, you can specify that for as long as the alternate greeting is enabled, Cisco Unity:
â¢Transfers callers directly to the greeting without ringing the subscriber phone when calls are transferred from the automated attendant or a directory handler to the subscriber extension. (The subscriber phone will ring if an outsider caller or another subscriber dials a subscriber extension directly.) This option is particularly well-received by subscribers who share a phone.
â¢Prevent all callers from skipping the greeting. In this way, you can increase caller awareness of a subscriber absence.
â¢Prevent all callers from leaving messages. By specifying that Cisco Unity will prevent all callers from leaving messages, you can help reduce mailbox size when a subscriber is out of the office and does not plan to check messages regularly.
Hope this helps!
