== Asterisk Configuration ==

=== Checking Modules ===
Make sure the modules "cdr_pgsql.so" and "res_config_pgsql.so" exist in /usr/lib/asterisk/modules/

* If not so, follow this document to compile them:
http://www.voip-info.org/tiki-index.php?page=Asterisk+cdr+pgsql

=== Make asterisk to load pgsql modules ===

Edit the file /etc/asterisk/modules.conf, and the state of these modules (cdr_pgsql.so and res_config_pgsql.so) to "load". (The default is "noload")

=== Set the config files to integrate with IBSng ===

Now we should make asterisk to join IBSng.<br>
<br>
First configure asterisk to load some tables in IBS dynamically.<br>
Append these lines to "/etc/asterisk/extconfig.conf":

 sipusers => pgsql,IBSng,asterisk.sip_buddies
 sippeers => pgsql,IBSng,asterisk.sip_buddies
 iaxusers => pgsql,IBSng,asterisk.iax_buddies
 iaxpeers => pgsql,IBSng,asterisk.iax_buddies
 extensions => pgsql,IBSng,asterisk.extensions

Note: sip and iax are used when we want to add these users via IBSng.


Then, edit the file "/etc/asterisk/res_pgsql.conf" to define the database parameters:

 [general]
 dbhost=x.x.x.x <= IBSng IP Address
 dbport=5432
 dbname=IBSng
 dbuser=asteriskuser
 dbpass=xxxx

We'll create the user (asterisk) in database later.

=== Restart Asterisk ===

Finally you have to restart Asterisk service to apply the changes.

== Database Configuration ==

First we'd better to define a new user in database for asterisk (we set it as dbuser in res_pgsql.conf before):

 # su - postgres
 createuser asteriskuser -P
 Enter password for new role:
 Enter it again:
 Shall the new role be a superuser? (y/n) <= y

'''Note: You can also limit this user to access "asterisk" table only.

Now, we should edit the file "postgresql.conf" to make postgresql (normally on IBSng server) to accept foreign requests.<br>
''Edit /etc/postgresql/XXX/main/postgresql.conf, and set "listen_addresses" to '*'.

Then, let the asterisk connect to database by adding the following line to /etc/postgresql/XXX/main/pg_hba.conf:

 host    IBSng   asteriskuser        x.x.x.x/32        md5

And, we should create asterisk table in database:
 
 cd /usr/local/IBSng/db
 psql -U ibs IBSng < asterisk.sql

Finally restart postgresql service to apply our changes. (Please make sure the IBSng service is stop during restarting postgresql.)

== Adding Asterisk as a RAS in IBSng ==
You can find the document [[RAS#RAS|here]].<br>
'''Note:''' Don't fill "radius key" field when you add this ras.
