PSX,
I'll start by saying I know nothing about SIP trunks and their providers.
What's the difference between those providers you listed versus say Cox Communications SIP offerings?
Cox is offering a dedicated SIP port (dedicated network connection with their network) for $100/month plus $6 per SIP trunk with unlimited local calling (I'd have to look it up, might include long distance too).
I know Scott wouldn't like this since it relies on my provider providing a dedicated network connection for this connection - making it harder to move to another location if there was a problem, etc.
Probably fine. They most likely are another L3 reseller.
Biggest difference is the location stuff. If you are local to their PoP, and odds are if you are talking with Cox they are the local cable provider, then they are local to you. So that means low latency to the SIP concentrators. Once on the concentrator that makes the calls flow that much better. Mind you, if you are with a reputable ISP, the links to the external providers is probably fine. But they could suffer on the backbone or cause latency somewhere else.
If they are offering it at $100 a month plus $6 per line, that's pretty competitive. That's ~$250 per month for a PRI equivalent. And if you get the pipe along with it? Pretty good.
Just determine if you need T.38 support, otherwise, that's not a bad way to go.
