Talking on a cell phone may not provide the best quality conversation, but it sure beats stopping off at a pay phone in the rain only to find no change in your pocket :-(
As for the CGs, I would imagine there are many who are put in charge of telecommunications despite having little or no experience with it. I don't guess that many small to medium size companies could or would justify hiring an on-site telecom professional to handle phone service issues. I've found that most managers have no idea just how complex telecommunications is and what's required to setup a phone infrastructure that meet's their company's needs. They leave it to the computer support staff to "figure it out".
So now we have a CG with no trining or experience in telecommunications making decisions (or at least making recommendations) about phone systems and telecom infrastructure. Is it a wonder why VoIP appeals to someone who may understand networking but not telecom. And, of course, someone is SELLING this technology to the ill-informed CG.
It's like anything else, a proper decision requires knowledge and expertise, which is something many on the network side don't have in the telecommunications arena. I doubt seriously that most technical folks want to screw up a phone system decision, its a matter of not being equiped make the correct choice.
And, yes, I do work in network/systems administration. I also manage telecom for my company. I have, however, tried to make it clear as to what I do and do not know and that I'll need outside assistance for some issues.
Just my $.02
