Unsolicited Voice Mode Result Codes
The form of the unsolicited result codes for voice mode is different from standard modem Command
mode result codes. The +V specification refers to these voice mode result codes as "event detection
reports". Event detection reports are provided in simple report format when one character is enough
to report an event, such as RING. A complex report format is used when one character is not enough
to report an event; generally, all multi-character responses. Complex event reports are in the format
<tag> <=> <data> <cr>, where <tag> is the data type, = is the ASCII = sign, <data> is a specific data
instance, and <cr> is ASCII 13 decimal.
Valid Complex Event Report Tags
Tag Description
TIME Caller ID Tag in the form TIME=HHMM, where HH is the hour (00-23) and MM is the
minute (00–59). All numbers are in ASCII and numbers less than 10 have a leading 0.
DATE The current date in the format MMDD (where MM is the month 0–12 and DD is the day
01–31). All numbers are in ASCII and numbers less than 10 have a leading 0.
NMBR The telephone number of the caller, in the format NMBR=<Number> or P or O (ASCII 4F
hex). The P indicates that the calling number information is not available since the
originating caller has requested Private service. The O indicates that the calling number
information is not available since the caller is outside of the area code.
NAME The caller's name in the format NAME=<Listing Name>.
MESG Indicates a data item not listed above in Multiple Message Format: MESG=<Data
Tag><Length of Message><Data><Checksum> in printable ASCII (to avoid confusion
with binary output).
ERRM Error Tag (used for Caller ID and other uses). Refer to the +VCID command.
DRON Distinctive Ring Cadence On time
DROF Distinctive Ring Cadence Off time
CPON Control Tone Cadence On time
CPOF Control Tone Cadence Off time
CWON Call Waiting Cadence On time
CWOF Call Waiting Cadence Off time
ASTB See Voice Mode Shielded Codes
SITT The data value for the SITT tag, in the format <SITT><=><data><cr>, where <data> can
mean:
ICNT Intercept Tone
VCCT Vacant Code Tone
REOT Reorder Tone
NCDT No Circuit Detected Tone
TON4 Fourth SIT Tone Number
TON5 Fifth SIT Tone Number
TON6 Sixth SIT Tone Number
TON7 Seventh SIT Tone Number
In the event of an unrecognized data tag, the SocketModem presents the data item information as
printable hex ASCII numbers following the MESG tag. For example:
RING
DATE=0321
TIME=1405
NMBR=5045551234
NAME=DOE JOE
MESG=060342424231
RING
