Asterisk Hangup

Filed under: Free/Open Source — Tags: , — jrasmussen0 @ 4:31 pm

I bought the ‘Asterisk: The Future of Telephony’ book to see about picking up some skills in a very neat Linux PBX system.  I’ve worked as the Project Liaison for a small company in Florida that purchased a $110,000 system that included lots a phones and 2 communicating PBX systems for 2 sites.  What I learned from that experience was that phone systems were nothing more than proprietary computer systems that offered very little innovation and lots of uptime.

Not to mention there seems to be a big difference in how much phone technology can cost.  It must all stem from a lack of competition and businesses willingness to spend tons of money on something they don’t understand very well.

Now Asterisk is matching and surpassing the telephony technologies in an open source software and hardware model.  The software model allows for businesses to maximize costs of consultants in a large ecosystem.

My current healthcare provider has purchased a big VOIP PBX system for our 600 devices over 5 seperated branches.  We are just using VOIP at our distant branches.  Our voice mail system isn’t anything to write home about and the Outlook module that allows for mail integration sucks and is out of date.

Anyway, I wanted to write down my biggest stumbling block trying to get Asterisk to start in a simple setup with an Ekiga softphone connected over SIP.  Apparently, you need to have these files in the /etc/asterisk/ directory.

  • extensions.conf — the dialplan file
  • sip.con — the sip configuration
  • modules.conf  — to tell asterisk to load the dialplan and sip modules automatically
    • [modules]
      autoload=yes

Unattended, A Windows deployment system: Welcome

We have implimented Microsoft's RIS at work and like the results pretty well. It would be neat to see how this compares.

FOSS Inventory tool for Windows — OCS

Filed under: Free/Open Source — jrasmussen0 @ 7:57 am

Debian and Ubuntu installation walk-through of ocsinventory. My contribution is to use 'sudo cpan -i XML::Simple Compress::Zlib DBI DBD::mysql DBD::mysql Apache::DBI'

OCSInstallation – Tomas3 – Trac

This is the errors that I received when I didn't have the cpan modules installed:

MySql config file successfully written

F/OSS Lessons:

Let this be another lesson for open source evangelism: Don't ever allow someone to install an older version of a product.

I was asked to install the older version of ocsinventory because the original version used all Microsoft products, MSsql server and built using Visual Basic. This worked pretty well for us but gave everybody the impression that the product sucked. It was difficult to convince my team to upgrade to the LAMP stack version (called ocsinventory-ng) because it wasn't worth putting more time into inventory. In fact, we ended up purchasing Microsoft's SMS 2003 license to replace the ocsinventory product.
