CA 2595992

An approach is described for providing shared trunking between a telephony gateway and an end office switch. The telephony gateway processes a packetized voice call, and interfaces a shared trunk to an end office switch (e.g., Class 5 switch) configured to switch calls over a circuit-switched telephone network. The trunk utilizes out-of-band signaling (e.g., Primary Rate Interface (PRI) signaling) in support of call establishment or teardown of the packetized voice call.

La présente invention a trait à une technique pour la fourniture de l'établissement de communications partagé entre une passerelle téléphonique et un commutateur de bureau terminal . La passerelle téléphonique assure le traitement d'un appel vocal paquetisé, et l'interfaçage d'une liaison partagée avec un commutateur de bureau terminal (par exemple, un commutateur de Classe 5) configuré pour la commutation d'appels sur un réseau téléphonique à commutation de circuits. La liaison utilise une signalisation hors-bande (par exemple, une signalisation d'accès primaire) pour le support d'un établissement ou d'un démontage d'appel de l'appel vocal paquetisé.
