Algorithm	Indicates the audio or video algorithm and protocol.
Frame per packet	The number of audio frames per packet that are transferred between the MCU
(audio only)	and the endpoint. If the actual Frame per Packets are higher than Frame per
	Packets declared during the capabilities exchange, a Faulty flag is displayed.

Resolution

(video only)

Indicates the video resolution in use. If the actual resolution is higher than resolution declared in the capabilities exchange, the Faulty flag is displayed. For example, if the declared resolution is CIF and the actual resolution is 4CIF, the Faulty flag is displayed.

Actual loss	The number of missing packets counted by the IP card as reported in the last
	RTP Statistics report. If a packet that was considered lost arrives later, it is
	deducted from the packet loss count. Packet loss is displayed with the following
	details:
	• Accumulated N - number of lost packets accumulated since the channel opened.
	• Accumulated % - percentage of lost packets out of the total number of packets
	transmitted since the channel opened.
	• Interval N - number of packets lost in the last RTP report interval (default interval is
	5 minutes).
	• Interval % - percentage of lost packets out of the total number of packets transmitted
	in the last RTP report interval (default interval is 5 minutes).
	• Peak - the highest number of lost packets in a report interval from the beginning of
	the channel's life span.
