Most providers simply connect to the tandem at the ILEC. The end office transit termination and origination cost is SO LOW that it doesn't make since to have a switch or access point at the end office. Since most things are ILEC if not all are VOIP everything is coming from a centralize switch point. Hopefully all the 1970's billing methods will disappear.
