 Dialing Prefix Parameters – Supports definition of prefix strings
indicating an inter-regional or international call. The algorithm
supports dialing plans where one specific digit is used as the prefix
for inter-regional calls, and two specific digits are used as the prefix
for international calls, where the first one is the same as the
inter-regional call prefix. It can also support dialing plans in which
the inter-regional prefix should be removed at the CPE before the
dialed number is transferred to the system. The dialing plan support
algorithm incorporated into the units operates as follows:
• If the Dialing Prefix Option is disabled the unit will insert the
Automatic Prefix (if defined) before the dialed number.
Otherwise it will be forwarded as dialed.
• If the Dialing Prefix Option is set to Enabled and the first
dialed digit differs from the Inter-Regional Prefix the unit will
insert the Automatic Prefix (if defined) before the dialed
number. Otherwise it will be forwarded as dialed.
• If the Dialing Prefix Option is set to Enable & Block
Inter-Regional Prefix and the first dialed digit differs from the
Inter-Regional Prefix, the unit will insert the Automatic
Prefix (if defined) before the dialed number. If the first dialed
digit is the Inter-Regional Prefix and the second one differs
from the International Prefix (indicating an inter-regional
call), the first digit (the Inter-Regional Prefix) will be removed
before forwarding the dialed number, thus blocking
inter-regional calls at the unit. Otherwise it will be forwarded
as dialed.
