Viewing Call Details
To display the details of a call, select a call whose details you wish to view and then click Show. The figures below display example details for a call.
| ● | Call Quality is not measured for PSTN legs, only for IP legs. Signaling and Trends tabs are displayed when a call is connected and media is transferred. |
| ● | The SBC device should be configured to send QoE Reports and Call Flow messages. |
Media CDR Fields
|
Parameters |
Description |
||||||
|---|---|---|---|---|---|---|---|
|
Media IP Address |
|
||||||
|
Media Port |
|
||||||
|
Burst Duration |
The mean duration (in milliseconds), of the burst periods that have occurred since the initial call reception. |
||||||
|
Rx Rate |
Shows the call's reception rate, in Kbps. |
||||||
|
Quality |
Voice quality: Good (green), Fair (yellow) or Red (poor). |
||||||
|
MOS |
MOS - MeanOpinion Score (specified by ITU-T recommendation P.800) - the average grade on quality scales of Good to Failed, given to voice calls madeover a VoIP network at the conclusion of the testing. |
||||||
|
Jitter (msec) |
Jitter can result from uneven delays between received voice packets. To space packets evenly, the jitter buffer adds delay. The higher the measurement, the greater the impact of the jitter buffer’s delay on audio quality. Two Jitter values are shown, one value for the caller side andone value for the callee side. |
||||||
|
Packet Loss (%) |
Lost packets - RTP packets that aren’t received by the voice endpoint for processing, resulting in distorted voice transmission. Two Packet Loss % values are shown, one value for the caller side and one value for the callee side. Packet Loss can be more than 100%. |
||||||
|
Delay (msec) |
Delay (or latency) - the time it takes for information to travel from source to destination (round-trip time). Sources of delay include voice encoding / decoding, link bandwidth and jitter buffer depth. Two Delay values are shown, one value for the caller side andone value for the callee side. |
||||||
|
Media Cluster |
Displays the name and index of the Media Cluster interface reported by the device. Example: , where n following the displayed name is the number indicating the Media Cluster's index used to facilitate network configuration. | ||||||
|
Media IF |
Displays the name and index of the Media Realm interface reported by the device. Example: SIMcmxLAN (n), where n following the displayed name is the number indicating the Media Interface's index used to facilitate network configuration. |
||||||
|
Network IF |
Network Interface Name. |
||||||
|
Coder |
Up to 10 coders (per group) are supported. See the device manual for a list of supported coders. |
||||||
|
SCE |
Method for conserving bandwidth on VoIP calls by not sending packets when silence is detected. True = Enabled (On), False = Disabled (Off). |
||||||
|
RTP Direction |
RTP Directional Control. Controlled internally by the device according to the selected coder. |
||||||
|
RTCP Direction |
RTCP Directional Control. Controlled internally by the device according to the selected coder. |
||||||
|
PTime (msec) |
Packetization time, i.e., how many coder payloads are combined into a single RTP packet. |
Call Media
The Call Media tab displays the media related CDR data that is retrieved from the SBC device.
The Call Signaling tab displays the Call Signaling CDR information that is retrieved from the SBC device.
Call Signaling
The Call Trends page tab displays calculated metrics data displayed across a timeline. You can toggle to display data for different metrics.
Call Trends
Open the Select Graphs drop-down to toggle to display different metrics.
The following table describes the CDR fields that are retrieved from the SBC.

Phone Number Before Map |
The original destination number (before manipulation, if any). |
|
Number Type |
The destination Type of Number (TON). |
|
Number Plan |
The destination Numbering Plan Identification (NPI). |
The following figure shows Call Details for a Correlated call. From the drop-down box, toggle between call legs to display call details for each leg.
Click the Call Flow tab to display the SIP message for the call. The following figure shows a Call Flow message (displayed under a separate tab). The Call Flow parameter highlighted below indicates whether a Call Flow message exists. Click PCAP File to download PCAP file.
The following figure displays an example for Calls Details with Privacy mode enabled for a Tenant Operator.
