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

Maximum number of dropped packets for all channels within a single call.

Packets

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.
