At the end of playback, you should have the option to give the message to another voicemail box...I think it is the 4 key...wait! I found a user guide.
This is from Nupoint Messaging User Guide, the embedded VM should work the same...
4 Give:
Give the message to another mailbox, distribution list, or off-system
telephone number.
The system will also give you the opportunity to record additional
comments before sending the message to someone else.
When you have added your comments, press 9 or the Send (or Exit)
softkey and continue your session.
Then press * to give the message to additional mailboxes if you wish.
I uploaded a Nupoint Messaging User Guide if you wish to look at it...
