Configure IP recording settings

Configure IP recording settings to tell the Recorder the settings to be used on NICs for the capture of calls. These settings include timing parameters, VOX detection Function of the IAFD product that compares a caller’s voice to one or more voiceprints in a watch list to detect if a target is participating in a call., RTP, and extension mapping settings.

Procedure

Click General Setup >Capture Settings > IP Recording.

Complete the following fields:

Item	Description
Timing Parameters
Call Timeout (seconds)	Type the number of seconds after which call recording will time out. This setting determines how long, after seeing the first RTP packet, that the IP capture engine will keep a call active before timing out. The call is timed out only if all streams involved in the call do not detect RTP for this duration.
Long Call Timeout (seconds)	Type the number of seconds representing how long the IP capture engine must keep a Speaker Call/Turret Call active, when no audio is detected, before timing out. Long Calls will be timed out only if all the streams involved in the call do not detect RTP for this duration. This setting does not apply to ACR Advanced Recorder.
Max Record Time (seconds)	This is the maximum time for which any given call should be recorded. Type a value in seconds. This setting does not apply to IP video recording. For IP video recording, specify the maximum video recording time from the settings screen of the IP Recorder Video server role Entity that contains a logical, predefined set of components (system software or certified third-party software) deployed in the Data Center and Site Zones that provide specific functionality for the system.. To access this settings screen, select System Management Module that allows performing suite-wide system management activities from a single, Web-based application, the Enterprise Manager. > Enterprise > Settings, and select the IP Recorder Video server role.
Long Call Max Record Time (seconds)	This is how long the IP capture engine will record a call before it breaks recordings into segments. See the Call Flow Guide for more information. Type a value in seconds. This setting does not apply to IP video recording. For IP video recording, specify the maximum size that a video recording can reach before it is broken into segments from the settings screen of the IP Recorder Video server role. To access this settings screen, select System Management > Enterprise > Settings, and select the IP Recorder Video server role.
Skinny No Audio Timeout (seconds)	Type the maximum number of seconds representing how long, from the Call Start message to the first Real Time Protocol (RTP) packet, that the IP Capture Engine keeps a call active before timing out. The call is timed out only if all the streams involved in the call do not detect RTP for this duration.
SIP No Audio Timeout (seconds)	Type the maximum number of seconds representing how long, from the Call Start message to the first Real Time Protocol (RTP) packet, that the IP Capture Engine keeps a call active before timing out. The call is timed out only if all the streams involved in the call do not detect RTP for this duration.
H.323 No Audio Timeout (seconds)	Type the maximum number of seconds representing how long, from the Call Start message to the first Real Time Protocol (RTP) packet, that the IP Capture Engine keeps a call active before timing out. The call is timed out only if all the streams involved in the call do not detect RTP for this duration.
Suppress Silence Recording
Silence Detection	The Suppress Silence Recording feature identifies periods of silence in order to prevent the recording of long periods of silence on speaker channels, allowing a reduction in the amount of storage space utilized. It is only intended for use in specific trading environments. Set the type of calls to which Silence Detection should apply. Long Calls—Silence Detection is only used for speaker calls. This should be used in production. All Calls—Silence Detection is used for all calls. This should be used only for testing purposes. Disabled—Silence Detection will not be used.
VOX Detection	Select this check box to use VOX as the method of detecting silence on the phone line. This setting should be used together with the Silence Detection parameter (above). G.711 VOX Detection is supported. VOX Detection should be enabled only when Silence Suppression is not enabled in the VOIP environment, and the audio codec in use is G.711.
Vox Detect Level (dB)	Move the slider to the left or right to reach the desired level of decibels for VOX detection. Default -45. This setting determines the sensitivity of the VOX detection algorithm in determining whether a sound should be considered audio, or simply low-level background noise and effectively rated as silence. VOX Detection must be enabled in order to use this setting.
Start Trigger Duration (milliseconds)	Defines the interval (milliseconds) when sound needs to be above the threshold before the VOX method identifies a call. The threshold is configurable on each channel. Change the value in increments of 28 by sliding the bar. Required. Range: 0 to 5000. Default: 250. Setting this value too low can cause occasional clicks or background noise to trigger recording. Setting the value too high can cause some audio not be recorded after a period of silence. This setting is similar to the Turn On time in TDM recording Recording environment where trunk-side recording taps directly into a T1 or E1 line to record all incoming calls at the demarcation point before going to a switch.. VOX Detection must be enabled to use this setting.
Stop Trigger Duration (milliseconds)	Type a value in milliseconds to determine how long a continuous period of silence must be detected for before recording stops. Setting this value too low can resulting in the call being stopped after even a small pause in audio. VOX Detection must be enabled in order to use this setting.
RTP Detection
Detect RTP	Choose a method to determine when to use Real-Time Protocol (RTP) detection to record calls. RTP detection works together with Recorder call control protocols and CTI. Options are: Always—RTP detection is enabled irrespective of any associated member group’s Recorder Fallback Type configuration. System Default—Behavior will be dependent on the associated member group’s Recorder Fallback Type configuration (set in Enterprise Manager). If any associated member group’s Recorder Fallback Type is set to “On CTI Disconnection (Performance)” or “Always (Liability),” RTP detection is enabled. Never—RTP detection is not enabled.
Extension to IP Mapping
Static Mapping	Select this check box to enable static extension to IP mapping—this will retrieve mapping from a static file within the system. If you want to stop recording on an extension removed from mapping, you must restart the capture engine. Static Mapping should be used only if specifically documented as required for the integration (check the appropriate integration guide) or under direct Product House guidance.
Persist Dynamic Mapping	Select this check box to stipulate that IP Capture update mapping dynamically. By default this is disabled.
Persist Interval (minutes)	Type a number representing the frequency in minutes at which to persist Dynamic Extension to IP mapping into the system. Typing 0 (zero) means this will occur as soon as an update is available. Typing 5, for example, means that the persist will occur once every 5 minutes.
