i) Voicemail
Voicemail (or voice matt, voicemail or VMS, sometimes called message
bank) is a centralized system of managing telephone messages for a large
group of people. In its simplest form it mimics the functions of an
answering machine, uses a standard telephone handset for the user
interface, and uses a centralized, computerized system rather than
equipment at the individual telephone.
Voicemail systems are much more sophisticated than answering machines
in that they can:
- Answer many phones at the same time
- Store incoming voice messages in personalized
mailboxes associated with the user's phone number
- Enable users to forward received messages to another
voice mailbox
- send messages to one or more other user voice mailboxes
- Add a voice introduction to a forwarded message
-Store voice messages for future delivery
- Make calls to a telephone or paging service to notify the
user a message has arrived in his/her mailbox
- Transfer callers to another phone number for personal
assistance
- Play different message greetings to different callers.

ii) Video conferencing.
A videoconference (also known as a video teleconference) is a set of interactive
telecommunication technologies which allow two or more locations to interact via
two-way video and audio transmissions simultaneously. It has also been called
visual collaboration and is a type of groupware.
