[asterisk-users] Is this failed Asterisk setup typical?

Hello

	I just read this article and would like some feedback from
experienced Asterisk users:

"Failed open source VoIP deployment leads to hosted VoIP strategy" By
Jessica Scarpati

"When budgets are crimped, open source voice over IP (VoIP) solutions
look attractive -- a little extra work for a lower cap-ex. But those
savings came at a high price for one Texas company, which -- after
years of struggling and failing to tame open source VoIP -- opted for
a hosted VoIP service from a local service provider.

[...] To harness the power of Asterisk and exploit the platform's near
boundless capabilities, you must have the in-house expertise to do so,
or at least bring in a well-vetted Asterisk consultant.

[...] CuDerm employees frequently collaborate with colleagues at two
partner companies while developing marketing campaigns for cosmetic
products. Three years ago, the company recognized that this frequent
collaboration would be more productive with direct inward dialing
(DID), DeRudder said, because users were spending too much time
retrieving and relaying individual phone numbers for incoming and
outgoing calls. [...] It wasn't until CuDerm adopted a hosted VoIP
service from Cypress Communications, an Atlanta-based service provider
specializing in hosted VoIP for small to medium-sized businesses
(SMBs), that simple conveniences such as call transfers became a
reality.

[...] Looking to reap the cost benefits of VoIP but avoid the expense
of buying and maintaining an IP-based private branch exchange (IP
PBX), DeRudder chose the open source VoIP project Asterisk. He chose
Asterisk because it required a custom-built server but no other
dedicated hardware for the phone system. The system was a perpetual
headache, DeRudder said. Bandwidth maxed out, users complained of
dropped calls and the main driver for the system, DID, never worked.

[...] Enterprises and SMBs sometimes overlook bandwidth needs and let
them take a backseat to cost savings in a hosted VoIP service, causing
call quality to suffer, Whelan said. Service providers may also offer
compression to squeeze more simultaneous calls in the pipe, but that
too can damage call quality, she added."

So it looks like this company had the following issues:
* No in-house technical expertise to set up and maintain Asterisk
* Not enough bandwidth
* DID module apparently not reliable

Based on your experience, are those problems typical?

Thank you.
