   GUI field	Description
   Enabled	Select to activate this configuration.
   Name	Enter a name for this configuration.
   Description	Select the category of calls you want to record: by phone number, department, user group, trunk, or queue.
   Caller number pattern	This option appears if you select By Phone Number for Description. Enter the number pattern to match the callers’ phone numbers following the pattern: ^[0-9XNZ]*[^\.]*$ where X=(0-9), Z=(1-9), and N=(2-9). For more information, see Configuring PBX options. The phone calls from the numbers matching the pattern will be recorded.
   Dialed number pattern	This option appears if you select By Phone Number for Description. Enter the number pattern to match the dialed phone numbers following the pattern: ^[^_][0-9XNZ\.]*$ where X=(0-9), Z=(1-9), and N=(2-9). For more information, see Configuring PBX options. The phone calls to the numbers matching the pattern will be recorded.
   Department	This option appears if you select By Department for Description. Select the extension department of which you want to record the calls. You can add a new department or modify an existing one. For more information, see Creating extension departments.
   Group	This option appears if you select By User Group for Description. Select the user group of which you want to record the calls. You can add a new group or modify an existing one. For more information, see Creating user groups.
   Trunk	This option appears if you select By Trunk for Description. Select the trunk of which you want to record the calls. You can add a new trunk or modify an existing one. For more information, see Configuring trunks.
   Queue	This option appears if you select By Queue for Description. Select the call queue of which you want to record the calls. For more information, see Creating call queues and queue groups.
   Direction	This option appears if you select By Queue for Description. Select the direction of call queue of which you want to record the calls.
   Record ratio	Enter the percentage of calls that you want to record. This value is a rolling percentage. In the following example scenario, FortiVoice records 50% of calls: Set the record ratio to 50. With a system that has no recorded calls, you are at 0% of recorded calls. The system records the first call. With the first call recorded, the record ratio is now at 100%. To reach the 50% record ratio, the system will not record the second call. With the record ratio at 50%, the system does not record the third call and the record ratio drops below 50%. With the record ratio below 50%, the system records the fourth call to achieve the 50% ratio again. To summarize this example scenario, the system has received four calls and recorded two calls to achieve the recorded ratio of 50%. The following settings can have an effect on the recorded call storage: Retention duration Archiving recorded calls Setting the file format for recorded calls
   Retention duration	Enter the days for which you want to keep the recordings.

Archiving recorded calls

Configure the settings to archive the recorded calls.

To configure the recording archive settings

1. Go to Call Feature > Call Recording > Archive.
2. Configure the following:

   GUI field	Description
   Rotation Setting
   Recording rotation size Recording rotation time	Enter the recorded file rotation size and time. When the file reaches either the rotation size or time specified, whichever comes first, the archiving file is automatically renamed. The FortiVoice unit generates a new file, where it continues saving recording archives. You can access all rotated files through search.
   Archiving options when disk quota is full	Specify what the FortiVoice unit should do if it runs out of disk space. Select Overwrite to remove the oldest archived folder in order to make space for the new archive, or select Do Not Archive to stop archiving more recorded calls.
   Destination Setting
   Destination	Select an archiving destination: Local: The FortiVoice unit’s local hard drive or a NAS server. Remote: A remote FTP or SFTP storage server.
   Local disk quota	If Local is the archiving destination, enter the disk space quota. The total disk quota for archiving calls cannot exceed 50% of the total storage disk size. For example, if the storage disk has a size of 100 GB, a maximum of 50 GB can be used for call archiving. If this quota is met and a new call must be archived, the FortiVoice unit either automatically removes the oldest call archive folder in order to make space for the new archive or stops archiving, depending on the Setting you specify under Rotation Setting.
   If Remote is the archiving destination, configure the following:
   Protocol	Select the protocol that the FortiVoice unit will use to connect to the remote storage server, either SFTP or FTP.
   IP address	Enter the IP address of the remote storage server.
   User name	Enter the user name of an account the FortiVoice unit will use to access the remote storage server, such as FortiVoice.
   Password	Enter the password for the user name of the account on the remote storage server.
   Remote directory	Enter the directory path on the remote storage server where the FortiVoice unit will store archived calls, such as /home/fortivoice/call-archives.
   Remote cache quota	Enter the FortiVoice cache quota that is allowed to be used for remote host archiving. The total cache quota for archiving calls cannot exceed 20% of the total storage disk size. For example, if the storage disk has a size of 100 GB, a maximum of 20 GB can be used for call archiving. If this quota is met and a new call must be archived, the FortiVoice unit either automatically removes the oldest call archive folder in order to make space for the new archive or stops archiving, depending on the Setting you specify under Rotation Setting.
   Schedule	Select a schedule for the archiving. Click Edit to modify the selected schedule or click New to configure a new one.
