NickPhone unifies all your numbers to one unique name (user's private e-mail address).
You just have to sign up and add the phone numbers where you are available. You also have the option to set rules for incoming calls.
The rules purpose is to direct the incoming calls (from NickPhone users) to one of your numbers according your private setting.
For example, a user can decide that during his work hours incoming calls from specific group will be redirected to the office, while incoming calls from another group will be redirected to another phone number.
By doing so you can separate your private calls from your work related calls.
NickPhone also gives a solution for outgoing calls.
Let's say you want to reach your friend, which may be available in 4 different phones. Instead of trying to reach him in every one of his phones, you can just call to his Nick and the call will be redirected to where he's available!
When you sign up, NickPhone automatically sync your contacts and finds out who's already a member!
