Sail and LDAP

SAIL and local LDAP address book lookup

Description

• This is a small howto for enabling LDAP lookup of incoming CID for your external calls.

• Yes, it will show NAMES on your IP phones if it matches name/number from your LDAP.

• These mods are NOT supported by Sail at the moment.

• This article may contain big inaccuracies, you're more than welcome to improve and correct it

• I can't be held responsible for any malfunction/damage to your system after these modifications.

• Note: you need gcc and the asterisk-devel in order to compile app_ldap-2

yum install gcc asterisk-devel phpldap-devel

Installation

• Download and install phpldapadmin following instructions found here: phpldapadmin

• Download and install app_ldap-2.0rc1

mkdir -p /usr/src/app_ldap2
cd /usr/src/app_ldap2
wget http://www.mezzo.net/asterisk/app_ldap-2.0rc1.tgz  
tar zvxf app_ldap-2.0rc1.tgz 
make install

• Note: you need gcc in order to compile app_ldap-2

Then open your browser and login to sme phpldapadmin page with admin credentials

For example:

https://myserver/phpldapadmin

Now expand the base DN which should be DC=mydomain,DC=myTLD and select "Create a new entry here"

Then, choose "Address Book Entry (inetOrgPerson)" and fill in the details for adding your first contact. I usually fill in Name, Surname and Work phone fields.

Edit ldap.conf into /etc/asterisk/

I edited this file in place as no template fragments seems to exist at this time. Add these lines:

[cidname]
host = localhost
version = 3
base = dc=mydomain,dc=mytld
convert = UTF-8, ISO-8859-1

edit mydomain and mytld to match your settings (for example: dc=contribs,dc=org)

Create a custom app into Sail

Create a new app in SAIL PBX -> Custom apps

Unique context name: your_app_name
Description: your_description
Span: EXTERNAL
Clutser: default

Code of the app:

exten=>s,1,LDAPget(MYCALLERID=cidname/${CALLERIDNUM})
exten=>s,2,GoTo(7000,1)
exten->s,102,GoTo(7000,1)
exten=>7000,1,NoOp(${MYCALLERID})
exten=>7000,2,Set(CALLERID(name)=${MYCALLERID})
exten=>7000,3,agi(selintra,Alias,SIP/5001 SIP/5002 SIP/5003,${EXTEN})
exten=>7000,4,Hangup

Where 7000 is an alias for ringing 5001, 5002 and 5003.

Please use values matching your current setup.

• Now edit inbound routes in your trunklines, select the custom app you created, et voilà!
