1. It doesn't connect to existing internal home wiring and telephone sets without a lot of extra cost. Only geeks and their tolerant mothers make computer calls.
Yamaha has a Volante RT57i broadband router, that allows you to plug in your analog phone, similar to Cisco's Analog Phone Adaptor (ATA). You can theoretically put a PABX behind that to route more calls if you have the bandwidth.
2. It needs QoS, and QoS ain't free. Look at Vonage. It's not free, and extra LD is >3 cents a minute. AT&T service through Sam's Club costs less than that!
QoS ain't free, but if you have tried VoIP, you'll know that the quality is decent without QoS. Overprovision of bandwidth has been the solution to QoS. Given that the amount of bandwidth used for VoIP is not very high, especailly with the newer codecs.
Business users may pay a premium for QoS, but individuals are likely to live with a "much cheaper" alternative, and switching over to a premium service when required.
3. You need a broadband connection for VoIP, plus you pay an extra charge. Think $30-$50 for broadband, and $15-$35 a month to the VoIP carrier which is what they charge for the QoS plus whatever the terminating carrier bills them for access to the PSTN.
It would be strange if people pays for broadband just to get VoIP. But for those whoa are already paying for broadband, VoIP is a cheap (if not free, like Free World Dial) alternative. PSTN termination problem still exist, but, more friends on VoIP means less termination charge.
4. By contrast, I beseech you ignorant slobs to check out an outfit called Cellsocket.com. They sell a doohickey that holds your cellphone. You plug it into your home wiring and disconnect your home wiring at the NID. Voila, all calls to and from your house go over the cellular network but you can use your regular home phones.
Interesting device, where I live, land call charges are cheaper than cell call charges. Anyway, with 802.11 (and 802.16), you have a hybrid cell phone that does both CDMA/GSM/TDMA and VoIP
Hmm..
It's just like water. You pay the utility company (phone company) to provide you with clean water (quality assured), and because it is a service, you pay some sort of tax for it.
Alternatively, you can get collect rain water, and pass it through a filter yourself (quality not assured). You pay a property tax for being in that area (ISP/bandwidth charge and Govt tax), if the tax is too high you can always move elsewhere (change provider).
Actually, Yamaha has a Broadband Router (RT57i) that allows you to plug in your normal analog phone. You just need to configure the the router (Web-based UI) to connect to any SIP server (e.g. Asterisk, Vocal, or even FWD(Pulver)) and your set for VoIP.
Cool.. but my Xbox does that as well...

I'm in a similar environment, 802.1x, PEAP/MSCHAPv2 (and DHCP)... Now I have to bring along UTP wires for my laptop running Linux... There is this "Aegis" client, but it doesn't seem to be working too well.. Anyone knows any other solutions out there?

But I'm afraid of vendor lock-in, so I'll rather use SIP/H.323
