I guess the SPAM folks are required to put "ADV" in the subject line. So lets do the math:
3 extra bytes TIMES about 200 SPAMS/day TIMES 2,000,000 internet users in MN TIMES 365 days/year * 8 bits/byte = an extra 3,263Gb of email traffic we don't need.
Those corporate phones will need to be connected to the land based system so the staff can call people that do not have IP phones. Once you are on the corporate IP network, you will have access to their voice gateway. You won't be limited to just their IP based phones.
Agreed, use a powered switch...
Plus, I have an "alternate" proposal for the powered switch--put an LED on all the wall jacks. Power the LED from the switch. When you walk into a room, and want to plug in, you can visually see which jacks are already hot...
Cisco, 3com, listening?
Think for a moment about service providers supplying the VoIP services. They will provide both the call routing (call setup) system, and the gateway service (so you can call grandma's 'old' phone, from your IP phone.)
The more customers that your provider signs up the more chance they have of _not_ having to route calls off-net. This is where the larger providers will get that "economy of scale". I can't help but smirk when I say that:)
Now think about this. Since the provider has two different customers, and can route calls only over IP, that implies there is some level of IP connectivity between two people or companies. Now I don't know how you hack a network with those Cisco phones, but I do know how you hack a network with a computer running a software phone--and some other tools:)
I think a single company that gets their own call manager (call setup) system, and their own gateway service, could implement a secure network--as secure as private line, anyway. I also think as the providers try to scale it up to multiple customers they increase the security problem.
