Asterisk and IBSng Integration

[ویرایش] Asterisk Configuration

[ویرایش] 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

[ویرایش] 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")

[ویرایش] Set the config files to integrate with IBSng

Now we should make asterisk to join IBSng.

First configure asterisk to load some tables in IBS dynamically.
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.

[ویرایش] Restart Asterisk

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

[ویرایش] 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.
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.)
