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. -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
