VOIP how is it done? Shabam 09-21-04

In order for VOIP to work, there must be a PBX switch at most locations
around the country, in order to convert the data packets back into analog
and be routed through the local phone lines. That way VOIP customers can
call analog phone customers.

Ok, so there are many providers out there, and I know they don't all own
such switches around the country. They must be either renting/leasing those
switches, or are just reselling. How does this work and which companies
handle this?

Second question. For internal routing, such as when VOIP user A calls VOIP
user B, the signal is obviously not being converted back into analog and
passed through the local phone company. My question is, how is the signal
able to find its way to user B? By IP address? What if user B's IP is
dynamic or he moves his IP phone to another network connection? I'm
guessing that whenever the phone is plugged in, it's sending a signal back
to the company telling it its IP address.

NuFone can do that for you.

Yes.

Not a problem. Most IP Phones or softphone "register" with the voip provider
and now the voip provider knows where they registered from and will continue
to send traffic to that ip address until that phone unregisters or can no
longer be reached.

No. Sipuras , IAXys , ATA186s are the devices that register using SIP or IAX
back to the VoIP provider. When someone needs to reach you the device will
attempt to "ring" your phone, if its not plugged in then your phone just
doesnt ring.


What are you looking to do with VoIP?

Supposed I wanted to start a service and create my own features and handle
my own billing. How would NuFone work with this?

Also, the rates seem a bit high, compared to someone I know who showed me
his price sheet. Is that for end users or resellers?
