NOTE:
This information element is encoded according to Figure 4-11/Q.931 and Table

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:
•
•
•
Dialing Prefix Option – Enables or disables the dialing prefix
support capability.
Inter-Regional Prefix – Defines the prefix indicating an
inter-regional call. This is also the first digit in the two digits
string indicating an international call.
International Prefix – Defines the second digit in the two digits
string indicating an international call.
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.
Valid options are: Disable, Enable, Enable & Block
Inter-Regional Prefix.
Default selection is Disable.
Valid values: One phone key-pad digit (0-9, *, #, A, B, C, D)
and X (no prefix).
Default value: 0.
Valid values: One phone key-pad digit (0-9, *, #, A, B, C, D)
