Arguments¶

• Channel

• ChannelState - A numeric code for the channel's current state, related to ChannelStateDesc
  

• ChannelStateDesc

  • Down

  • Rsrvd

  • OffHook

  • Dialing

  • Ring

  • Ringing

  • Up

  • Busy

  • Dialing Offhook

  • Pre-ring

  • Unknown

• CallerIDNum

• CallerIDName

• ConnectedLineNum

• ConnectedLineName

• Language

• AccountCode

• Context

• Exten

• Priority

• Uniqueid

• Linkedid - Uniqueid of the oldest channel associated with this channel.
  

• SSRC - The SSRC identifier for the remote system
  

• PT - The type of packet for this RTCP report.
  

  • 200(SR)

  • 201(RR)

• From - The address the report was received from.
  

• RTT - Calculated Round-Trip Time in seconds
  

• ReportCount - The number of reports that were received.
  The report count determines the number of ReportX headers in the message. The X for each set of report headers will range from 0 to 'ReportCount - 1'.
  

• SentNTP - The time the sender generated the report. Only valid when PT is '200(SR)'.
  

• SentRTP - The sender's last RTP timestamp. Only valid when PT is '200(SR)'.
  

• SentPackets - The number of packets the sender has sent. Only valid when PT is '200(SR)'.
  

• SentOctets - The number of bytes the sender has sent. Only valid when PT is '200(SR)'.
  

• ReportXSourceSSRC - The SSRC for the source of this report block.
  

• ReportXFractionLost - The fraction of RTP data packets from 'ReportXSourceSSRC' lost since the previous SR or RR report was sent.
  

• ReportXCumulativeLost - The total number of RTP data packets from 'ReportXSourceSSRC' lost since the beginning of reception.
  

• ReportXHighestSequence - The highest sequence number received in an RTP data packet from 'ReportXSourceSSRC'.
  

• ReportXSequenceNumberCycles - The number of sequence number cycles seen for the RTP data received from 'ReportXSourceSSRC'.
  

• ReportXIAJitter - An estimate of the statistical variance of the RTP data packet interarrival time, measured in timestamp units.
  

• ReportXLSR - The last SR timestamp received from 'ReportXSourceSSRC'. If no SR has been received from 'ReportXSourceSSRC', then 0.
  

• ReportXDLSR - The delay, expressed in units of 1/65536 seconds, between receiving the last SR packet from 'ReportXSourceSSRC' and sending this report.
