Table 2: Key performance indicators

KPI	Comment
T1ChannelsActive	Total number of T1 channels currently in use in the target device

TollBypassCall	Identifies a call where the caller is an internal extension, managed by the

	external PSTN Number, with one or more following criteria: - Outbound
	call - Off-net call - The call is going through a PSTN Gateway and caller site
	and PSTN Gateway site are different - An intersiteLegacyPBXCall can be
	also a TollBypassCall, if the PSTN Gateway site is different from the caller
	site. - TollBypass calls are interesting to save money for long distance or
	international calls using a remote PSTN Gateway with local fees7
	Example: A caller in Boston makes a call to an external PSTN number base
	in London. Because there is an IP-VPN between the Boston office and the
	London office with a PSTN Gateway in London, the call goes through the
	IP network until the Londons PSTN Gateway.
