The Avaya Contact Recorder (ACR) creates audio files of calls that have occurred on your telephone system. Providing the ACR recordings are no longer taking place, these recordings can be migrated to VFC using the ACR Import Source.
The ACR Import Source migrates both ACR-only and ACR+15.2 systems using the native ACR API.
Both encrypted and unencrypted ACR recordings can be migrated by the ACR Import Source.

Creating an ACR import source
Follow the steps in ACR before creating a a new Import source:
...
Configuration Item | Description |
|---|---|
| Name | Name your Import Source. This name will identify the source across the system. |
| Type | Select ACR |
| ACR Hostname or IP Address | Mandatory. Name of ACR CRS (Central Replay Server) |
| ACR Port | Mandatory. Port Number of ACR CRS (Central Replay Server) |
| TLS Certificate File or Thumbprint | Optional certificate file / certificate thumbprint used for the ACR connection. |
| TLS Key File | Optional file system location where the certificate key is stored. |
| TLS Key Password | Specify the password for the file that contains the certificate keys. |
| TLS Trust List | Certificate chain (or Chain of Trust) is made up of a list of certificates that start from a server's certificate and terminate with the root certificate. If your server's certificate is to be trusted, its signature has to be traceable back to its root CA. |
| ACR API User | Mandatory. ACR user that must be created with API permission before this Import Source is used. |
| ACR API Password | Mandatory. ACR user password that is set the first time the Import Source is used. N.B. The ACR API user must not have a password set when it is created, instead the import source ACR API Password will be set and used automatically. |
| ACR Layout Name | Mandatory. ACR search layout name created before this Import Souce is used. |
| Lua CDR Customisation | Optional. Lua script to be executed during VFC CDR creation from ACR call that allows filtering and control of the import. See elsewhere on this page for more details. |
| ACR Timezone | Mandatory. Set to the timezone of the ACR CRS, in case it is in a different timezone from the ingesting VFC server. |
| Maximum Recording Length (minutes) | Mandatory. Maximum length of any single ACR recording to be ingested. Recordings exceeding the maximum length may not be ingested or an alert generated. While a larger batch size retrieves more records, it must not exceed the duration of the timeslot available for processing. |
| Recording Start Timestamp | Mandatory. Start timestamp of the first ACR recording to be migrated. |
| Recording End Timestamp | Mandatory. Timestamp of the last ACR recording to be migrated. |

Lua CDR Customisation
As historical recordings may include changes in field layout, data anomalies caused by software bugs and ultimately may not be required due to business re-organisation, embedded Lua scripting has been provided to control the migration process.

function demo_mod.Split(s, sep)
local fields = {}
local sep = sep or " "
local pattern = string.format("([^%s]+)", sep)
string.gsub(s, pattern, function(c) fields[#fields + 1] = c end)
return fields
end
return demo_mod
Import Policy Configuration
Follow the steps below to configure the Data Import action:
...
Configuration Parameter Name | Description |
|---|---|
| Enable Recording Rules | Specifies if all data should be processed in the imported data set or just the records of the recorded users as configured in Verba |
| Execute Only on Selected Servers | If enabled, a specific server can be chosen that will run this policy |
Types of alerts raised by the ACR Import Source
Alert Message | Explanation |
|---|---|

Failure to process Call Metadata | Unexpected or unavailable ACR call metadata values. |
| Failure to communicate with ACR | Firewall or network configuration problem. |
| No more ACR recordings available | Batch start time exceeds the last ACR recording timestamp. |
| Detected no recorded parties in a recording | No recording owner found in customer custom metadata. |
| Failed to retrieve media from ACR | Media unavailable or download interrupted. |
| Unable to find expected ACR call metadata | Either standard or ACR extended call metadata could not be extracted. |
| Could not obtain time zone offsets | Timezone offsets could not be extracted from the VFC database. |
Migration Status Reporting
No report files are generated, however at the end of each batch, a notification alert is raised containing details of recordings migrated from ACR into VFC.
