# with the cheapest rate. If no carrier is found for this NPANXX
|

# Here is the SQL to create the lcr table:

|
#
|
|
# create table if not exists lcr (
|
|
# npanxx mediumint not null,
|
|
# rate varchar(10) not null,
|
|
# carrier_string varchar(20) not null
|
|
# );
|
|
# alter table lcr add unique index (npanxx, rate, carrier_string);
|
|
#
|
|
# A typical npanxx from this table should look like:
|
|
#
|
|
# mysql> select * from lcr where npanxx='734223';
|
|
# +--------+--------+----------------+
|
|
# | npanxx | rate | carrier_string |

# | 734223 | 0.0064 | SIP/provider1 |
|
|
# | 734223 | 0.0076 | SIP/provider2 |
|
|
# +--------+--------+----------------+
|
|
#
|
|
# Unfortunately these rate sheets are not in a standard format.
|
|
# You will have to write a custom loading script to populate this table.
