Method and system for supporting shared local trunking
First Claim
Patent Images
1. A method comprising:
- receiving a request for capacity from a user;
determining respective Rate Center (RC)/Public Safety Answering Point (PSAP) combinations for respective users in a plurality of users, wherein the RC/PSAP combinations are based on a rate center and a public safety answering point that are commonly assigned to one or more users in the plurality; and
allocating one or a plurality of channels within a trunk based on the determined RC/PSAP combinations,wherein each of the one or plurality of channels is allocated to the respective users in the plurality according to respective RC/PSAP combinations,wherein the trunk is shared among the plurality of users.

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.
