Users can transfer calls direct to another user's mailbox. In some cases they can do this using standard controls provided by their phone, in which case refer to the appropriate telephone user guide.
For users whose phone does not provide its own control for voicemail transfer, you may be able to add a programmable button set to the voicemail transfer. After pressing the button, the user's current call is put on hold and the user can then enter the target extension number to indicate the mailbox required.
