Multiple Appearance Directory Numbers
Call Transfer
Call Forward
Conference
Trunk-to-trunk calls
Attendants
Multiple Appearance DNs are charged on the meter assigned to the Prime DN
(PDN). Data calls are charged to the originating telephone. Maintenance tests
on metered trunks do not affect the metered values.
Only the party originating the Call Transfer is metered.
On calls where the Call Forward feature is used, the last party to forward the
call is metered. This applies to cases where a CO call originates from a Call
Forward station, and to cases where an established CO call is transferred to a
station that is forwarded to another internal station.
Only the party originating the Conference Call is metered.
Metering of trunk-to-trunk calls using an outgoing CO trunk is not supported
if the trunk access code is a one- or two-digit access code. Otherwise, a meter
corresponding to the trunk access code of the metered trunk route is
incremented. Only three- and four-digit codes are supported for DNs or trunk
access codes.
For attendant-originated calls to CO trunks, the attendant meter is
incremented. When the call is extended, the attendant is metered until a
telephone within the Meridian 1 is added to the conference. When the
attendant uses a loop key, the call is metered to the Room DN connected
through that key; otherwise, the attendant meter is incremented.
