Chapter 3. Using the gateway
Description
String to unify received phone
numbers, for SMSC routing and
to ensure that SMS centers can
handle them properly. This is
applied to 'sender' number when
receiving SMS messages from
SMS Center and for 'receiver'
number when receiving messages
from SMSbox (either sendsms
message or reply to original
message). Format is that first
comes the unified prefix, then all
prefixes which are replaced by
the unified prefix, separated with
comma (','). For example, for
Finland an unified-prefix
"+358,00358,0;+,00" should do
the trick. If there are several
unified prefixes, separate their
rules with semicolon (';'), like
"+35850,050;+35840,040". Note
that prefix routing is next to
useless now that there are SMSC
ID entries. To remove prefixes,
use like
"-,+35850,050;-,+35840,040".
Load a list of accepted senders
of SMS messages. If a sender of
an SMS message is not in this
list, any message received from
the SMS Center is discarded. See
notes of phone number format
from numhash.h header file.
NOTE: the system has only a
precision of last 9 or 18 digits of
phone numbers, so beware!
As white-list, but SMS messages
to these numbers are
automatically discarded
