- a network;
a plurality of network clients;
a plurality of network resources shared by the network clients, the network resources including at least one of a trunk or a server port, conferencing or MCU channels, gateway channels, media-on-hold ports, IVR ports, unified messaging ports, recorded announcements, recording ports, DTMF detection ports, call parking slots, or pilot numbers to applications, wherein at least one of said network clients includes an access request unit that is configured to send an access request message to at least one of the network resources, wherein the network resource sends the network client a busy message if the network resource is busy; and
an Accessing Busy Resources (ABR) service, wherein said access request message includes a request for a referral to the ABR service if the network resource is busy, wherein said busy message includes an address of the ABR service, wherein said access request unit can subscribe, using the address, to said ABR service responsive to receiving the busy message and be informed by said ABR service when said shared network resource is available,wherein said access request unit is configured to specify one or more conditions required of said network resource when subscribing, by sending a subscription request message including at least one conditions field,wherein said ABR service de-subscribes the network client responsive to the shared network resource being available.

Abstract
An Accessing Busy Resources service is adapted to receive subscription requests from clients for notification of when a busy resource is free, and to monitor network resources to determine if they are free. Upon notification, the Accessing Busy Resources service de-subscribes the client. The network client devices include Access Request units which make requests to access services and receive notification when the services are available.
