Latency  | Designates value that is an estimate of the network latency, expressed in  | 
  | milliseconds. This value represents the average value of the difference  | 
  | between the NTP timestamp indicated by the RTP Control Protocol  | 
  | (RTCP) messages and theNTP timestamp of the receivers, measured when  | 
  | these messages are received.Cisco CallManager obtains the average by  | 
  | summing all the estimates then dividing by the number of RTCP messages  | 
  | that have been received. Value of the Latency in   | 
  | comes from the CMR table. Its set only once the call is established. This  | 
  | metric is only available for IP Phones.  | 
  | 
  | 
Local  | Identifies a call where the caller is an internal extension and where the callee  | 
  | is a Local External PSTN number, according to the Numbering Plan  | 
  | (NANP or Other prefixes). A Local call is also:- An Outbound call - An  | 
  | |
  | PSTN Gateway is involved in the Voice path  | 
  | Note: Internal extensions are managed through the UBA.xml adaptor  | 
  | configuration file, where the variable ExtensionRange is defined. In order to  | 
  | be able to know whether or not a call will be charged as a Local call, an  | 
  | additional variable needs to be set in the UBA.xml adaptor configuration  | 
  | file. If the first N digits match for this particular site with one of the number  | 
  | configured in this list, then the call is tagged as Local  | 
  | 
  | 
LongDistance  | Identifies a call where the caller is an internal extension and where the callee  | 
  | is a LongDistance External PSTN number, according to the Numbering  | 
  | Plan (NANP or Other prefixes). A Long Distance call is also: - An  | 
  | Outbound call - An   | 
  | TollBypassCall if a remote PSTN Gateway is involved in the Voice path  |
