Aisling-
Yes, I've been wondering about this part of the system too. I'm at a small local ISP, and have a few customers currently connecting through me to some of the SIP providers (Vonage, NuFone, etc.) but have been thinking about putting up my own PSTN gateway. It just seems like a really big hassle though, working out the various agreements and getting PRI's and all that. So I was looking for an easier way, and stumbled across this:

...AT&T is one of our backbone providers, so it seems like a great idea to me. If I'm reading this (sparse) documentation right, it seems I can just set up my asterisk server to send H.323 to them and they will worry about the routing from there. Right? Of course, I don't know what their rates are looking like, but I thought I'd ask everyone around here...has anybody used this service, and could share their experience? Or can anybody see potential pitfalls with doing things this way?
Thanks
Hunter.

Hi all,
Could someone let me know the most common way that an Internet ISP
would allow customers access to the PSTN?? Do they buy multiple fxo
cards such as the TDM400P and rent multiple lines from a larger
provider??
Would the best way be to connect to a third party voice/pstn gateway?? Is that simply a matter of forwarding all sip traffic destined for the pstn to another provider with a gateway and then they have to worry about the number of lines etc??And if that is the case, I presume no extra hardware is required?
Thanks, Aisling.
