At the time this document was created, Switzernet is running about twenty SIP servers in production environment. These servers emulate the behavior of a Porta-SIP server. The aim of this replacement was to be able to configure the servers as we need instead of being limited by the Porta-SIP’s limitations like the lack of configuration possibilities. For example, in order to ban some IP addresses, it is needed to reboot the server after modifying the configuration file of OpenSer in Porta-SIP. All Porta-SIPs were replaced by Astrads.

To ease the deployment of new servers, a system installation and configuration manager was installed. The tool chosen for this task was Puppet [doc]. It provides a way of automated installation and/or configuration of all servers and makes the process of updating to newer versions easier. This is also done automatically. Each Astrad version is a module that can be installed in an empty machine or on a machine with a previous version installed.

Here is the version evolution record of our astrad configuration. :

Astrad 001

Astrad is the name for ASTerisk and RADius

An Astrad server is an Asterisk server on which we included the RADIUS protocol to communicate with our Porta-Billing.

This first version includes an automated installation of the first version [doc] of the manual installation.

Plus the two following updates:

- Update of management of vocal messages [doc]

- Update of calls billing with Asterisk and Porta-Billing [doc]

Astrad 004

This release provides an alternative way of authentication for call initiation. This alternative is used when the Master server is unavailable.

The replication server db2 is used.

Here are the details on the script used:

http://www.switzernet.com/3/public/110328-astrad-alternative-radius-auth

Other changes and corrections:

- ast-resend-lost.pl

o Error in date formats

The function format_date_gmt is rewritten and is renamed to format_date_sql_2_gmt.

The issue was:

This function formatting dates in ast-resend-lost.pl was using dates extracted from MySQL as if it was at GMT time zone.

But dates in MySQL are at local time zone. It was creating wrong packets with bad hours in all time parameters.

o Incomplete H323-conf-id parameter

Radius packets had an error in one of its parameters.

The name missing 'h323-conf-id=' has been added in front of H323 conf id value.

The Porta-Billing was unable to match messages sent by this script with standard ones.

o Transmission Delay

Acct-Delay-Time has been added in Radius requests from this script.

- agi-rad-auth.pl + extensions.conf

o Missing remote IP address parameter

Radius requests were generated without including source ip address.

It has been added.

Astrad 005

In this release we have added the Realtime module, the local database of asterisk is used to allow outgoing calls (sipusers table) or incoming calls (sippeers table).

These tables are replicated from the master server MySQL-Astrad DB3 [http://switzernet.com/3/public/110405-db3]

The updating of registrations on the master-billing is carried through federated tables ‘location2’ in Astrad and ‘location’ in db3.

With this update you need only two Perl script (daemon) for accounting (start-stop) and for resend lost packets.

Astrad 006

Astrad 013

As Lenny in now in EOL, all repositories have been changed to Debian archive repositories.
