V7_JCF[CV >J] Assign a non-empty value to this variable to specify that Job Control Files are to be written with an entry for every item in a job. The default for version 8 is to write only the first FS filename followed by single line containing the negative value of the count of files.
VALID_ASCII_EXTS[CV >C] Assign a white-space-separated list of file extensions (each with a leading '.') to this variable to specify allowable file types which are to be treated as faxable if they appear to contain ASCII data. ASCII files with other file extensions will be rejected. When this variable is not defined, all such files will be treated as faxable ASCII files.  Files with extensions .TXT, .ASC and .CVR are always treated as faxable ASCII files and are not affected by this variable.
VARGROUPS_USED[SRO] Provides in an FS file a string of digits 0 to 9, and letters from A (=10) to U (=30) for higher numbers, recording the history of the use of variable groups.
VCARDNO [SW] This is a 'smart' system variable to which a credit card number can be assigned for checking. If valid, the value is placed in the CARDNO system variable (see above). If invalid, the CARDNO variable is set to an empty value. You can determine whether the card number was valid by testing if the value in CARDNO is the same as the value you just assigned to VCARDNO. This variable is only available if your CopiaFacts system includes the Credit Card option.
VCEXPDATE [SW] This is a 'smart' system variable to which a credit card expiration date ( MMYY) can be assigned for checking. If valid, the value is placed in the CEXPDATE system variable (see above). If invalid, the CEXPDATE variable is set to an empty value. You can determine whether the expiration date was valid by testing if the value in CEXPDATE is the same as the value you just assigned to VCEXPDATE. This variable is only available if your CopiaFacts system includes the Credit Card option.
VMAIL_INDEX [SRW] This variable should be set to a value between 1 and the number returned by VMAIL_SCAN (inclusive) to reference an entry in the table of message files created by referencing VMAIL_SCAN. If the number assigned to the variable is outside this range, the values returned by VMAIL_NAME and VMAIL_INFO will be empty. The VMAIL_INDEX variable is set to one when you reference VMAIL_SCAN, unless (a) there are no mail message files, in which case it is set to zero or (b) the VMAIL_START variable has been set to last in which case it is set to the number returned by VMAIL_SCAN.
VMAIL_INFO[SRO] After referencing VMAIL_SCAN and setting VMAIL_INDEX to a valid value, this variable contains information about the voice message file referenced, in the format described below. Otherwise, the value is empty. You may substring this variable and reference the components in $play_var commands (with custom algorithm files) to describe the file to the caller. The format of the information returned is YYYYMMDDHHMMWS, where YYYYMMDD represents the date of the file, HHMM the time of the file, W the day-of-week of the file (Sunday=1), and the remaining characters in the value are the file size in bytes. The provided VMAIL.ALG sample algorithm file will speak the day, date and time from this variable string in US or UK English.
VMAIL_MIN [SW] This variable sets, for the remainder of the call, the minimum voice message file size in bytes, below which a message will be considered as 'noise' and deleted during a message scan. The default value is 4000, which represents just over a second in the normal recording format of 6kb ADPCM.
VMAIL_NAME [SRO] After referencing VMAIL_SCAN and setting VMAIL_INDEX to a valid value, this variable contains the full pathname of the voice message file referenced. Otherwise, the value is empty. You may reference this variable on a $image_desc command to play back the message to the caller.
VMAIL_SCAN [SRO] This variable returns the number of voice messages found in the current recorded message directory. Each time you reference this variable it re-scans the directory to obtain the names of all the message files and sorts them into call number sequence. File names and file information may then be retrieved using the VMAIL_NAME and VMAIL_INFO system variables, after you have set the VMAIL_INDEX variable to reference the specific table entry.
VMAIL_START [SW] This variable can be set to a keyword of last to start from the most recent message after a VMAIL_SCAN. Any other value of assigned to this variable is treated as first, which is the default. This variable also affects the sequence of playback of messages initiated by a $type playback infobox or selecting the infobox defined in $playback in the user profile. The setting lasts for the remainder of the call or until a new value is assigned to this variable.
VMSG_DIR [SW] You can set this variable to a new directory name you wish to use for CopiaFacts voice messages. The change takes place immediately and is effective until the end of the call or until changed again. If the value is not a valid directory name, the change will not be made. This feature allows you to change the language in which the call messages are spoken as a result of caller input in a question box. The variable name may also be specified as VMSGDIR, without the underscore. If there is no FAXFACTS.DIG file in the appropriate directory, the existing filename will not be changed.
VOICE_DELAY [SW] Sets a value in minutes for the delay between voice outbound attempts when infobox logic transfers to state VOICE_RETRY. The value may be preceded by a prefix of 'A' to indicate that the alternate phone number is to be used on the next attempt. If no delay is specified, a default value of 3 minutes is used.  A value must be assigned to this variable (using $set_var) during the call to be effective.
VOICE_PARMS [SW] For calls transferred using $type transfer commands, values of the form "parm=number" may be assigned to this variable to set parameters for the current call transfer only. If any values are set, all $cpb_parm values in the configuration file are ignored for the call. The parameters are applied to the outbound call, not the incoming line, for SC-Bus transfers in which a second line is used. See the examples shown for $dial_cmd, and the list of parameters for $cpb_parm.
VOICEBC_HANGUP [SWS] Assigning a value in seconds to this variable in an infobox or FS file will cause a hangup by the called party in a voice broadcast to be treated as a successful conclusion of the call if the call duration exceeds the specified value. Assigning a value of 0 causes all calls to be treated as successful if the called party has hung up after connection. Assigning a keyword of fail will cause the call to be failed with outcome code 94 on hangup by the called party: this is the default. It is possible to assign different value at different times in an infobox sequence.
VOIP_DTMF_INBAND[CV >E] Set this variable to a non-empty value to enable DTMF in-band detection (tones), which is no longer the default for Copia VoIP Ports. This variable should be set in the FS file for output calls, or in the USR file controlling an inbound call.
VOIP_DTMF_MININTERVAL[CV >E] Set this variable to the minimum number of milliseconds to be allowed between tone detections for in-band DTMF tones on Copia VoIP Ports. The default value is 40.  In practice the resolution for this value is currently 20ms, and reducing the value to 20ms may still not detect auto-generated tones near the minimum intervals specified by ITU Q.23.This variable should be set in the FS file for output calls, or in the USR file controlling an inbound call.
VOIP_DTMF_TRIGGER[CV >E] Set this number to the sequential number of the RFC2833 packet signalling a DTMF tone which is to be used as a trigger.  The default is 1 to trigger on the first packet for a tone after the end of the previous tone.  See the discussion in the Copia VoIP Ports topic.This variable should be set in the FS file for output calls, or in the USR file controlling an inbound call.
VOIP_FROM_NAME[SRO] This variable contains the SIP Display Name, if available, for incoming calls to Copia VoIP Ports. The first 21 characters are also placed in the ANS log file field.
VOIP_FROM_URI[SRO] This variable contains the full SIP URI for incoming calls to Copia VoIP Ports.
VOIP_MUTE_MS[CV >E] Set this variable to the number of milliseconds for which audio is to be muted after detection of either incoming DTMF or silence on the original half of a linked call on linked Copia VoIP ports.
VOLUME [SW] Set the playback volume for the remainder of the call or until a new assignment is made. The assigned value is added to the value set by the $volume command, if any, and the result set to the nearest point in the range -10 to 5. A value of -10 represents a reduction of 20db in the standard volume, and 5 represents an increase of 10db.
