# agi-IVR_recording_verification.agi      version 2.6
#
# This script is designed to function as a complete automated 3rd party 
# verification IVR recording system. This script will work by optionally asking 
# for a company ID and/or a customer phone number, then it will play through the 
# listed prompts asking for a single digit press (i.e. 1 for a yes or a 3 for a 
# no, hash/pound/star/zero/0 are not accepted only 1-9 is valid for these steps).
# All data for these calls will be logged to the vicidial_ivr table as well as 
# optionally to a log file  in the standard astguiclient log file directory 
# and/or STDERR output on the asterisk process. This script uses the 
# /etc/astguiclient.conf file for database connection settings, logging data and
# for logfile path information only.
#
# With a modified VDAD agi transfer script, this script could also be used to do 
# automated outbound surveys as well. Feature under development.
#
# ; 1. the DNIS or inbound number called 
# ; 2. play the recording ID (Y|N) with prompt leading up to it
# ; 3. record this call(Y|N)
# ; 4. ask for a company code(Y|N) with the number of digits in that company code and the prompt
# ; 5. ask for a user code(Y|N) with the number of digits in that user code and the prompt
# ; 6. ask for the customer phone number(Y|N) with the number of digits in that phone number and the prompt (Y-10-85100001)
# ; 7. speak the current date (Y|N) with prompt announcing the date
# ; 8. a dash-delimited list of prompts that expect responses(85100002-85100003)
# ; 9. a "your recording ID is..." prompt (85100004)
# ; 10. logging/output (FILE|STDERR|BOTH|NONE)

# CHANGELOG
# 70912-1105 - First build, non-functional
# 70916-2331 - functional alpha version, reads all prompts and logs data, no recording yet
# 70921-1110 - full beta version with recording working
# 71028-1122 - added say datetime as an option
# 71112-0238 - added prompt delays and date announcement message
# 71120-1337 - added playing of recording ID at beginning of session
# 120430-2214 - Converted call to Monitor app to be asterisk 1.8 compatible
# 130108-1816 - Changes for Asterisk 1.8 compatibility
# 250924-2158 - Added code for deprecation of "Monitor" application after Asterisk 20
# 251006-0901 - If recording_dtmf_muting enabled, force use of MixMonitor for recording
