The real fight may be over walled gardens vs open standards.
This podcast describes a similar situation using commercial software that embraces open standards.

"Don Reece the Director of Information Technology at Pembina Trails, a Public School Division in Winnipeg, Manitoba, Canada joins the Lippis Report podcast to discuss his newly installed unified communications implementation. Pembina Trails has an enrollment of approximately 14,000. They have a network of dark fiber backbone between sites running at 1 Gigabit, Microsoft Active Directory and Exchange, Dell Ethernet Switches and a very old voice system. It was time to upgrade the voice system, so they did it with Objectworld's Unified Communications Server and saved over $200K while offering a state-of-the-art IP telephony system. Don goes into all the details. It's a great listen. Enjoy Nick."
Open Source is not useful if the protocols used in them are closed and not in wide use. In that case one silo is replaced with another silo.
This podcast describes how Pembina Trails School Division ignored Cisco VOIP and opted for open-standards based commercial software. Their reasoning? They could use any switch, any SIP phone, any gateway, and integrate with any other SIP based system using open standards. While it does describe my employer's software the reasoning could apply to any standards-based install, including Asterisk.
Fair warning is that they replaced it with unified communications software from my employer. While my employer sold them the core server software they could pick and choose all the other components as they saw fit, from platform to phones to networking equipment.
What made this possible is the SIP protocol, which is why I included Henry in this email. Without SIP this would be impossible. Thank Henry for this effort.
The kicker is that if we screwed up and didn't meet expectations they could move over to Asterisk or another commercial vendor without changing any hardware. It could be done in a weekend. This of course keeps us on our toes and enforces a discipline that is woefully absent from the PBX industry, which is still acting as if it was the DEC PDP-11 era when we are in fact in an era of personal supercomputers. We designed our software to be SIP down to its bones, unlike Asterisk, which is ultimately based on its own protocols. One key point: Asterisk is not free. It requires expertise to set up and expertise to manage as like all Linux based applications it comes as a platform for enthusiasts and experts, and requires care and feeding.
The advantage of commercial software that uses open standards is that it allows for investments in areas such as automation and ease of use. This lowers the bar such that these systems can be installed and managed by non-technical people. This eliminates a key cost of running computer systems. O'Reilly and Associates might well be the perfect site for an Asterisk deployment. An accountant's office isn't. A key goal that I laid out three years ago was that our software could be fully maintained by a receptionist, the real power behind the throne in all small offices. Never, ever piss off the receptionist.
Give a listen. Don is an honest broker and keeps us on our toes.

Since then, we've enjoyed asterisk's enormous flexibility. If there was ever a sweet spot for open source, it's VoIP, and I'm surprised that more people haven't been paying attention to Asterisk and Freeswitch (another open source pbx.) There are huge cost savings possible, and the flexibility and control that comes with both open source and VoIP really make it possible to make your voice communications part of your digital toolbox, rather than some anachronistic backwater. I never listen to voice mail on my phone any more. It's really sweet to get it as an email attachment, and to be able to forward it as easily as any other email. And programming phone applications is finally starting to get out of the stone age. If your org isn't using asterisk, it should be. I'll also point out that the implementation is relatively painless. And if you have trouble, there are good books available, including ones from yours truly :-) Meanwhile, this message reminds me to make the same offer I've made for past O'Reilly conferences. The first five IP readers to respond can get a free pass to the O'Reilly Emerging Telephony Conference to be held February 27 to March 1, 2007 at the San Francisco Airport Marriott. The conference doesn't focus exclusively on Asterisk, but there's a lot of Asterisk-related content, including a keynote from Mark Spencer, the founder of Digium and the creator of Asterisk, as well as some great sessions on asterisk and VoIP techniques, including the launch of a new framework for programming Asterisk on Ruby. Another very cool session at the conference is a workshop entitled Calls in the Utility Computing Cloud - Experiments in on demand ultra scalable telephony Using Amazon EC2 and S3 - This is freeswitch and Asterisk both - This is really exciting stuff. They are using Ec2 to create on demand scalable phone networks - something that was not possible before. You basically had to over-specify and pray your network never reached capacity. For more information about the conference, see http:// conferences.oreillynet.com/etel2007/ The actual program is at http://conferences.oreillynet.com/pub/w/50/ schedule.html (For some reason, Mark Spencer's keynote isn't listed, but the conference chair reassures me that he will be there.) To get one of the free passes, send email to Kathleen Bruno - kbruno () oreilly com -- and tell her about the message on IP. Kathleen is on holiday; back in the office Thursday Jan 4, so don't expect an immediate reply. Also, here's a 15% discount code you can use if you aren't lucky enough to get one of the free passes: etel07tim For more details on the conference, see http:// conferences.oreilly.com/etel. To register using the IP discount, send email to Kathleen Bruno, kbruno at oreilly.com. She's still on holiday till tomorrow, but will get back to you as soon as possible to let you know if you were one of the first responders. _________________________________________ Tim O'Reilly, Founder & CEO, O'Reilly Media, 1005 Gravenstein Highway N., Sebastopol, CA 95472 +1-707-827-7150 http://tim.oreilly.com ------------------------------------------- ----------------------------------------------------------------------- You are subscribed as slavitch () gmail com To manage your subscription, go to http://v2.listbox.com/member/?listname=ip Archives at: Archives: http://archives.listbox.com/247/Modify Your Subscription: http://v2.listbox.com/member/? & Unsubscribe: http://v2.listbox.com/unsubscribe/?id=3566138- aec10944-7i7vpn4i
