A list of phone number prefixes

which are accepted to be sent
through this SMSC. Multiple
entries are separated with
semicolon (’;’). For example,
"040;050" prevents sending of
any SMS message with prefix of
040 or 050 through this SMSC.
If denied-prefix is unset, only
this numbers are allowed. If set,
number are allowed if present in
allowed or not in denied list.

denied-prefix

A list of phone number prefixes

which are NOT accepted to be
sent through this SMSC.

preferred-prefix

prefix-list

As

denied-prefix

, but SMS

messages with receiver starting
with any of these prefixes is
preferably sent through this
SMSC. In a case of multiple
