Claim 7:
8. An apparatus comprising:, one or more memories;, one or more network interfaces; and, one or more processors, wherein the one or more processors are configured to:
obtain, via the one or more network interfaces, an indication that a telephone call is parked in an Internet Protocol (IP) communication system;
determine, from first data stored in the one or more memories, a physical location of one or more Push-To-Talk (PTT) user client devices of the IP communication system;
determine, from second data stored in the one or more memories, an organizational group of a user of each of the one or more PTT user client devices of the IP communication system;
determine a first organizational group based upon the first organizational group being associated with where the telephone call is parked in the IP communication system;
generate a first PTT channel based upon the physical location of the one or more PTT user client devices , wherein the first PTT channel includes a first subset of the one or more PTT user client devices that belong to the first organizational group;
provide, via the one or more network interfaces to the first PTT channel, a first PTT audio notification that the telephone call is parked in the IP communication system;
obtain, via the one or more network interfaces, an indication that the telephone call has not been answered by a user of a PTT client device in the first subset of the one or more PTT user client devices;
generate a second PTT channel based upon the physical location of the one or more PTT user client devices, wherein the second PTT channel includes a second subset of the one or more PTT user client devices that is different from the first subset of the one or more PTT user client devices; and
provide, via the one or more network interfaces to the second PTT channel, a second PTT audio notification that the telephone call is parked in the IP communication system.
