Abstract: A method to allow certain types of adjunct applications for telecommunications networks that require caller interaction during call setup to temporarily access the adjunct and then be released back to the network for routing to the final destination. Specifically, when the call enters the network, the network originating switch redirects certain calls to the adjunct. The adjunct may be locally homed directly off the originating switch or may be homed remotely off a centrally located switch. Once the call has been routed to the adjunct and caller interaction has been completed, the adjunct releases the voice connection back to the switch which then routes the call to its final destination.

Abstract: An arrangement for routing toll calls to a predominant local exchange carrier (LEC) or to a competitive access provider (CAP). An egress switch of an interexchange (toll) carrier translates the called directory number office code to determine whether that code serves a CAP. If so, an exception table is searched to identify the CAP. If the called number is not in the exception table, the call is routed to the predominant LEC. Calls may also be routed to a customer who is served by a CAP and the predominant LEC via either of these local carriers. The billing record identifies an originating and/or a terminating CAP for the call. Optionally or alternatively, an ingress IXC switch may access a data base to determine the CAP or predominant LEC serving a called customer. The ingress IXC switch then routes the call to an IXC egress switch serving the carrier that serves the called customer. Advantageously, this arrangement efficiently serves calls using a CAP to provide part of the connection.
