This is an example of the hardware that allows this, not an example of where
it's used, but the technology exists and is certainly in use for all sorts
of interesting solutions:

Didn't say it had to be TDM.
I am a VoIP end-user. I pick up my desk phone to make a call, and my PBX
routes it. It might go:
* To a local PSTN gateway, and out over traditional TDM (or analog) lines,
or
* To a commercial gateway provider, or
* Direct to the other end's PBX as a 'native' VoIP call
In either case, it might get there over
* Private, dedicated IP networking, or
* The Internet.
The 6 sextants are "who operates the gateway" multiplied by "who owns the
wires I use to get there".
Cheers,

Hey,
Does anyone know anyone / have any contact information for ATT Wireless
engineering, or (even better) is there an ATT Wireless engineer who would mind
contacting me off-list? We're seeing a problem with call routing to certain
NXX, but only when forwarding calls to TNs in that NXX.
Thanks,

I have been asked by management to find options to bring in an external
auditing company to evaluate our network and provide appropriate
recommendations.
We are a small telecommunications company looking for firms with experience
in Voice (VoIP) security audits, as well as general security experience
appropriate for a Broadband ISP, with an internal corporate network.
We're located in the southern US (Oklahoma).
Public and private recommendations are welcomed.
Thank You,
