ABSTRACT:
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.
