Prefix Dialing Table
Description
The Prefix Dialing Table supports several features. On analog CO Lines, the table is used to
determine the cost of the call. For ISDN Lines assigned Enblock dialing and SIP Trunks, Enblock
dialing can be supported so that you don’t need to wait for the inter-digit time-out to send digits as
a block to the ISDN or SIP service provider. Up to 500 Prefix numbers and associated entries are
available in the table.
When employed for calculating the cost of a call, the system will compare the outgoing digits
dialed with the Prefix Table entries (maximum 8 digits). If the first dialed digits match the entry,
the cost of the call is determined using the Prefix Dialing Table. The Call Charge timer assigned
in the table for the Line is used in-place of meter pulses along with the Cost per Meter Pulse
assigned in the system database. The cost is then calculated as:
(Call Duration/Call Charge Timer) * Cost per Meter Pulse.
When used for Enblock dialing, the first digits you dial are compared to the Prefix digits. If the
digits match, when you dial the maximum number of digits assigned, the number is immediately
sent to the service provider as a block. If there is no match or the maximum digits count is not
reached, the system will wait for the inter-digit time before sending the digits. For an ISDN Line, a
minimum number of digits can be defined. Even if the Prefix digits match, the call will not be
processed until the minimum number of digits is dialed.
Each Line is assigned a Table Id which must match the Prefix dialing Table entry to be
considered for the specific Line.
