I work for a CLEC.  For our VoIP service we offer the customer a choice of how we handoff to the customer.  Customers can pick POTS, PRI, CT1, or SIP handoff.  Calls are SIP from our IAD/CPE device at the customer (usually an Adtran box w/SIP) all the way to our core.   Many carriers do this, there is nothing special about it.
