The display of address information between the first RING and the
second RING can be disabled by setting ATS84.4=1. The term
[Prefix] is a predefined number string to be added in front of the
Calling-party-number before sending it to the DTE. This is useful for
some automatic dial-back-up systems. The number string can be
assigned as follows:

• ATCI<Prefix> - When and only when the type-of-number

denotes an international number will this "Prefix" be added to the
Calling-party-number before indicating it to the DTE.

ATCI<> - Disables the international number prefix-adding
function. (Default)

ATCN<Prefix> - When and only when the type-of-number
denotes a national number will this "Prefix" be added to the
Calling-party-number before indicating it to the DTE.

ATCN<> - Disable the national number prefix-adding function.
(Default)

incoming calls. This can be done by setting the bit 0 of S-register
S118:

S118.0=0 - Enable the TA to answer a call (by default).

S118.0=1 - Disable the TA to answer any call.
