Field Descriptions for All Calls Table
The following table provides brief descriptions of all fields in the
All Calls
table.
Table 11-1. All Calls Table Field Descriptions
Table Column Description
Protocol H.323, SCCP, SIP, or UNKNOWN. A protocol type of UNKNOWN means
that Surveyor recognizes media packets but does not recognize related sig-
naling packets for a call. For the UNKNOWN type, the monitoring point may
not be able to see the signaling packets or the signaling protocols may not be
supported by Multi-QoS.
Frame ID Frame ID of the first frame from which the conversation was detected. This
field is useful when doing post capture analysis. If there is a need for in-depth
analysis of a specific call, the first frame associated with the call can be
quickly determined.
User R Factor Voice quality measure expressed as a numeric value between 0 and 94. The
value is calculated by Surveyor. Surveyor uses a formula that includes
packet loss, jitter, transmission delay, and recency to determine the User R-
factor.
Network R Factor Voice quality measure expressed as a numeric value between 0 and 94. The
value is calculated by Surveyor. Surveyor uses a formula that includes
packet loss, jitter, and transmission delay to determine the Network R-factor.
Jitter Maximum jitter, measured in milliseconds, for all channels within a call. The
value is calculated by Surveyor. Surveyor uses the formula described in RFC
1889 to calculate jitter.
Dropped Packets Maximum number of dropped packets for all channels within a single call.
The value is calculated by Surveyor.
RTCP Jitter Maximum jitter, measured in milliseconds, for all channels within a call. This
is the jitter value reported in RTCP packets.
RTCP Dropped
Packets Maximum number of dropped packets for all channels within a single call.
This is the number of dropped packets reported in RTCP packets.
Status Status of the call. The Status is either “Active” or “Complete”.
Source Address The IP source address of the initiator of the call.
Dest Address The IP destination address of the receiver of the call.
Start Time Time at which the call was started.
Stop Time Time at which the call was complete.
Call Setup TIme Time that was taken for the call to be setup (the time taken from the start of
the call until the phone rings).
Total Call Time Duration of the call from Start Time to Stop Time.
