Passive recording is a recording method when recorded media streams are retrieved from the network traffic by monitoring the network Mirror/SPAN/TAP port on the network switch.
Terminating recording is a recording method when recorded media streams are sent by some device directly to the recorder (e.g. BIB enabled Cisco phones, SIPREC enabled device or similar protocols).
The following steps are assumed to be already completed:
CLI (Command Line Interface)
|GUI (Graphical User Interface)|
Passive VOIP (hw voip) channels
For this example, we assume that Administrator enabled only hw voip installed in the system. After reload, Administrator can expect following channel list.
|Navigating to Setup->Channels->VOIP->Edit will show the following screen:
Enabled: enables/disables channel (only if dynamic license group is set)
Name: channel description
License Group: set channel license group
Compression: set channel compression codec: MLAW (default), ADPCM, or GSM
Source: Recording Source. Use this parameter to differentiate channel display (phone,radio,mic) on live monitoring screen.
Record Rx/Tx Streams: How to record Rx/Tx streams. Record single stream (mixed, Rx only or Tx only ), single recording will be created. Or all streams (mixed, Rx and Tx), three separate recordings will be created.
No RTP Timeout: Recording will be halted if receiving no RTP packets during this timeout (seconds).
Generate DTMF tone: Generate and inject DTMF tones from RTP packets (rfc2833). Available options: near-end (Tx stream), far-end (Rx stream), all or none. (Default value: none)
Handle DTMF event: Handle DTMF tones (trigger DTMF start/stop, append digits to dialed/callerid fields) from RTP packets (rfc2833). Available options: near-end (Tx stream), all ( Rx and Tx streams). (Default value: near-end).
Addressing: Defines what address to use to identify channel traffic, MAC or IP
MAC Address: MAC address ("XX:XX:XX:XX:XX:XX"). This parameter is used if Addressing is set to MAC.
IP Address: IP address ("XXX.XXX.XXX.XXX"). This parameter is used if Addressing is set to IP.
Protocol: Signaling protocols: SIP, SCCCP, H323, MGCP, UNISTIM, UAUDP, LYNC, AVAYA, NEC
CTI Link: Use CTI Link (None, or JTAPI)
Map to Extension: Map to extension from CTI Link
Set Extension: Retrieve extension from signaling and update recording field.
Break recording when ON HOLD: When recording put on Hold, VOIP RTP stream is closed and recorder has two options:
One option creates a single long recording with silence during hold, the other option creates multiple recordings
ON_HOLD timeout: Stop recording after timeout if no RTP traffic during On-Hold state.
WAN IP Address: Try to use external IP address if no recording sessions, created according information received from SDP, found for current RTP packet. This is applicable only for channels with SIP signaling protocol.
Open Individual channel in configuration mode.
Display current channel setting.
Display configuration commands available for this channel.
For details about parameters common to all types of channels - refer to config channel Common Parameters
|Command Format||Description||Extra Notes|
|address [mac|ip]||set address type (mac,ip)||Defines what address to use to identify channel traffic, MAC or IP|
|breakonhold [y|n]||break recording on hold event(default y)||
When recording put on Hold, VOIP RTP stream is closed and recorder has two options:
One option creates a single long recording with silence during hold, the other option creates multiple recordings.
|mac [00:00:00:00:00:00]||set mac address||MAC address associated with this channel|
|ip [000.000.000.000]||set ipv4 address||IP address associated with this channel|
|nortptimeout [1-10]||set no rtp timeout (sec). default 3 secs||Session considered lost if no RTP received during this time|
|setext [y|n]||set extension (retrieved from signaling protocol)||Try to get extension from the call signalling(used with sip, sccp, lync)|
|onholdtimeout [1-30]||set no rtp after onhold event timeout (min, default 15 min)||
applicable only when breakonhold = n
|protocol [none|sip|...]||set channel signaling protocol (proto ?, list all available signaling protocols)||none - RTP only
