Ah -- so there's a central voip line for 911?  911 voip dispatch?
it seems the protocol for identifying location would be an open
thing, making the location recording redundant. -- a well defined
out of band channel would carry the info.  Is 911 routing
standardized from SIP or is it per-provider?  that is, do fwd and
braodvoice and whatnot all do it the same?
