The conventional phone is fixed. It's on your
desk and if you are not there it is of precious little value. The phone line,
the phone number and the telephone itself are locked into a fixed relationship.
Each is dependent on the other two.
A VoIP phone does not suffer this limitation;
the telephone number, the telephone and the network are all decoupled. You
simply log-in to any VoIP-enabled phone connected to the internet and your
calls follow you there. You may be familiar with retrieving your e-mails from
any computer connected to the internet anywhere in the world; VoIP telephony is
similar.
So, when you are away from your office, your
phone number goes with you. You could also pack up your bags and move to
another location anywhere in your office (or the world) temporarily or
permanently, without having to forward your calls.
Assigning telephone numbers to out of hours and
designated on-call service staff and managing the calls is easy with VoIP
telephony.
