Asterisk can be used as Soft Switch (among many other things). Freeside can examine recorded CDR data for subscriber billing purposes.

cdr_pgsql

Call detail records are stored by asterisk (by means of the cdr_pgsql extension) into a database of our choice. We will need to edit /etc/asterisk/cdr_pgsql.conf, add the asterisk user to postgres, add rights for asterisk to access the cdr table, and verify settings actually work.

cdr_pgsql.conf

This is our example config file. You will need to change the password to suit your install. 

; Sample Asterisk config file for CDR logging to PostgresSQL

[global]
hostname=postgres
port=5432
dbname=freeside
password=FIXTHIS
user=asterisk
table=cdr               ;SQL table where CDRs will be inserted
spool=pgsql.spool

pg_hba.conf

This pg_hba.conf sample is only a snippet of the ACL to permit asterisk to connect.

hostssl (or host)
The connection type.
10.14.0.0/24
This example is a class C subnet.
md5
Password authentication required
hostssl         asterisk        freeside        10.14.0.0/24              md5
Check for sql access from the asterisk server
pghostname is the postgres host where freeside is running.
pbx:~$ psql -h pghostname -U asterisk freeside
Password for user asterisk:
Welcome to psql 8.1.11, the PostgreSQL interactive terminal.

Type:  \copyright for distribution terms
       \h for help with SQL commands
       \? for help with psql commands
       \g or terminate with semicolon to execute query
       \q to quit

SSL connection (cipher: DHE-RSA-AES256-SHA, bits: 256)

freeside=>

Check for storage results in the sql table. 

freeside=# SELECT acctid,calldate,src,dst,duration,billsec,disposition from cdr;
 acctid |        calldate        |     src    |    dst      | duration | billsec | disposition
--------+------------------------+------------+-------------+----------+---------+-------------
      1 | 2008-02-20 15:40:00+00 | 8005551212 | 18004664411 |       19 |       0 | NO ANSWER
      2 | 2008-02-20 15:48:52+00 | 8005551212 | 18004664411 |       14 |      10 | ANSWERED
(2 rows)

freeside=#

If needed, /var/log/asterisk/messages or the asterisk interactive cli will provide reporting for any errors.

Error logs here were from insufficient GRANT permissions to asterisk (as a Pg user). 

Feb 20 15:37:40 ERROR[3404]: cdr_pgsql.c:159 pgsql_log: cdr_pgsql: Failed to insert call detail record into database!
Feb 20 15:37:40 ERROR[3404]: cdr_pgsql.c:160 pgsql_log: cdr_pgsql: Reason: ERROR:  permission denied for sequence cdr_acctid_seq
Feb 20 15:37:40 ERROR[3404]: cdr_pgsql.c:161 pgsql_log: cdr_pgsql: Connection may have been lost... attempting to reconnect.
