My apologies up front for such a long post.
As an ex Nortel engineer for 15 years, I’m continually amazed that companies will fork out $100K+ for a phone system, plus licenses, plus support, plus PRI lines, when much cheaper options are available.
The main thrust for most PBX vendors is that Asterisk is unstable and unproven, whereas their product Just Works. Five years ago, that may have been true, but most people don’t know of the massive improvements in the last few years.
Naturally, the PABX vendors exploit this to their advantage, and further coax their clients by telling them that their system is ‘IP capable/upgradable’, should they want to pursue that option later on.
What most clients don’t ask, is how much it costs to buy additional cards for extra users, extra PRI capacity, extra licenses for analogue & digital sets, VOIP card, etc. and that’s where the vendors really gouge the client.
Take for example, you have a Nortel Option 11c, and you want to add another 4 users and a fax line, but your system is currently at capacity.
You’ll need to buy:
A digital line card for 16 phones - they don’t come in any other variety = $4000
A FALC (analogue) card - $2500
Extra digital licenses - the price escapes me, but it’s not cheap
Extra analogue licenses - as above
(The prices may be slightly out of date, and are priced for the Australian market. YMMV)
Proprietary Digital phone - from $350+
Time and cost of an engineer to install and configure all of the above.
If your users require voicemail, chances are you’ll need to buy more CallPilot licenses, plus additional licenses per user should they want ‘advanced’ features such as a web interface for voicemail, without even mentioning the additional servers you’d need.
Want to add VOIP ? No problem, please buy:
Media card
Signalling server
ITG card
With the examples above, it’s unlikely you’d get much (if any) change from $10,000 and that’s simply to provide a basic phone and voicemail.
Pretty soon, the phone system becomes an unwelcome guest, and rather than working with the business, it becomes a parasite.
Now for all the Nortel purists out there who cry ‘but the CS1K obviates all that additional hardware’, true, but you’re still hammered for licenses and support, and unless you’ve attended a Nortel course, there is small chance the client is going to know how to configure up an extra phone or add features like BLF to M3904.
And you’re still paying to buy freaking dongles, for crying out loud. If that doesn’t show a stagnant mindset, I don’t know what does.
And Nortel isn’t the only offender.
Until recently, Cisco paid lip service to SIP functionality (helloooo, SCCP), making it as difficult as they could to integrate their phones and ATA’s with Asterisk. Whilst the latest update for the 942’s comes some way in resolving that, the latest phone just released by Cisco is still playing hard to get with anything but a SPA9000.
Asterisk is unproven/unstable ?
Some of the major VSP’s over here that are using clustered Asterisk boxes, with failover redundancy would disagree with that statement.
So, really what makes Asterisk a viable commercial system is the fact:
- it is fairly stable (the telecoms industry has a much higher standard of stability than the IT crowd, so what is fairly stable in telecoms is usually rock solid in IT parlance),
- it is easily updated via the Internet, as opposed to a planned outage late at night with a vendor trained engineer
- supports a wide range of SIP and analogue phones
- has basic call centre functionality out of the box
- users can see what is happening with their system, instead having being runaround by the telco
Basically, it does what few systems before have done - it empowers the end user.
People are sick of not knowing why their phone system doesn’t work, or paying for hardware locked kit.
They also hate having to pay $$$ to a telco/vendor just to add some basic functionality to the phones.
Want 2 line presentation on your phone ? $30, thank you.
Want to change the diversion to mobile from 4 to 6 rings ? $30, thank you
Want to change the name on the phone ? $30, thank you
With a medium sized company, this quickly adds up to hundreds of dollars per month, and the galling part to the client is, when it takes someone like me all of 2 minutes to access and change it, it’s hard not to feel ripped off, huh ?
Asterisk gives CIO’s, IT managers, technicians, SOHO users, team leaders, etc. the functionality and accessibility they asked for decades ago, but were blindsided by the vendors for years.
But don’t expect a friendly response from the traditional PBX vendors though.
Most of them view Asterisk as a ‘toy’ system, others see it as a threat.
However, I have a several hundred clients who would not only dispute that, but would never go back to a key system or proprietary phone system ever again, simply because Asterisk provides more functionality to them than their previous system that cost 4x the price.
Sorry for the long post, but I hope it addresses some of the questions you had.
