NMBR NMBR = <number> or P or O where <number> is the telephone number
of the caller, where P indicates that the calling number information is not
available since the originating caller has requested private service, and
where O indicates that the calling number information is not available or
out of service at the calling location.

MESG MESG = <data tag> <length of message> <data> <checksum> in printable
ASCII hex numbers. This tag indicates a data item not listed above. The
message is only possible for Multiple Message Format.
The modem does not present any Caller ID information if the DCE detects a checksum error in
the Caller ID packet.
In the event of an unrecognized data tag, the modem will present the data in ASCII hex numbers
following the MESG tag.
Setting AT#CID=2 will cause the modem to report CND information in its ASCII coded
hexadecimal raw data format. The DTE software is responsible for explaining the data.

Distinctive Ring

Distinctive Ring is a phone service that may be offered by your phone company. Check
your phone company for availability. With this service, you can have several phone
numbers assigned to the same phone line. The phone company will send a different type
of ring signal for each phone number being called. The subscriber can distinguish which
number is called by which type of ring is received.
A simple use of this feature is that you can have three numbers on the same line and you
can list the three numbers for voice, data, and fax, respectively. You can then have your
fax machine answer only the ring corresponding to the fax number and have your modem
answer only the ring corresponding to the data number. The voice call will not be
answered by either fax machine or data modem and it will only be answered when
someone picks up the phone. Or you can have the answering machine answer only the
voice ring. A more complicated use is that you can have one number for multiple uses,
such as one number for both data and fax.
The ring types supported and the corresponding ring cadence detect criteria are:
Type
1

The RI output waveform is the same for all ring types detected, e.g., RI is on for the
total duration of the ring period.
