Usage
If you set to restricted, either restricted or unrestricted transmission
facilities are used to complete the call. A restricted facility is a
transmission facility that enforces 1's density digital transmission (that is,
a sequence of 8 digital zeros are converted to a sequence of 7 zeros and
a digital 1).
If you set to unrestricted, only unrestricted transmission facilities are
used to complete the call. An unrestricted facility is a transmission facility
that does not enforce 1's density digital transmission (that is, digital
information is sent exactly as is).
Usage
Enter y to restrict other users from reading or canceling the voice
messages or retrieving messages via Voice Message Retrieval.
