Call Routing Service. The Call Routing Service provides for the identification of the carrier to whom a call is to be routed when a toll-free (0+000-XXX-XXXX or 0+000-XXX-XXXX) call is originated by Customer. This function uses the dialed digits to identify the appropriate carrier and is done by screening the full ten digits of the dialed number. The Call Routing Service may be provided in conjunction with a Customer’s InterLATA or IntraLATA Switched Exchange Access Service. When 800 Call-Routing service is provided, an originating call is suspended at the first switching office equipped with a Service Switching Point (SSP) component of the SSC/SS7 Network. The SSP launches a query over signaling links (A-links) to the Signal Transfer Point (STP), and from there to the SCP. The SCP returns a message containing the identification of the carrier to whom the call should be routed and the call is processed. Requesting Carrier may obtain Call Routing Service pursuant to the rates, terms and conditions specified in Ameritech FCC No. 2 Access Tariff.

The SCP returns a message containing the identification of the carrier to whom the call should be routed and the call is processed. CLEC's SS7 network is used to transport the query from its End Office to the Ameritech SCP. Once CLEC's identification is provided, CLEC may use the information to route the toll-free traffic over its network. In these cases, Ameritech Switched Access services are not used to deliver a call to CLEC. The toll-free carrier ID date may not be stored for CLEC's future use.
