Its a wierd double standard, most poeple are thinking the copper loop is the gold standard, its not infact most of ontario is delivered via fibre loops then in to voip switches and the last mile becomes copper from the co pops.
Many companies offer a varied spin on a virtual pri. So there is no set terminolgy one can go by when hunting for the perfect package. Things to look for when lookng for SIP trunks or vPRI's etc.. is the abiltiy to set your own caller id, and the actual volume it can handle. Many companys sell vpris and trunks on the knowledge you will never use all the channels simulataniously so you can end up with a bad line ration. (lots of homework to be done when getting larger things like this :) ) If your a call center, make sure you do ample research first. Copper trunks can be cheaper when comparing the price of internet+phone lines, but there are many advantages of sip trunks for office most people dont consider.. Here is just 1 benifit of many. Imagine a small company with 4-5 offices 10 emps each if they host 1 phone server at a colocation with a sinle voip trunk all the offices can connect via cheap dsls to the central colocation voip switch and smoke the cost of multiple phone lines at multiple locations (you can probably pick out 3-4 more benifits just from reading this scenario :) )... Remember there is always multiple solutions for every scenario, some not as plesant as others :) for those interestd in a less present approach visit the nortel forums.
