One of the features that can be provided with signalling system #7 is selective
call acceptance and selective call rejection. With these features, you can
place specific directory numbers on a screening list, and if that number
calls your number, it will either be accepted or rejected depending upon
the feature. A rejected call will get a message that you are not accepting any
calls, while the accepted call will ring your phone.

There are some really nice features in store for the future!
