Problems solved by technology
Initiating a push-to-talk session to a mobile / wireless user who is not available simply results in a negative response tone.
What it cannot do, however, is establish a push-to-talk session with a push-to-talk enabled computer that is not registered with any operator's PTT service.

Embodiment Construction
[0024]FIG. 2 is a block diagram of an illustrative embodiment of a system consistent with principles of the present invention. The system (200) includes an IP data network (208) of a wireless push-to-talk service provider, as described in FIG. 1, with one or more wireless phones (202, 203, 205) having push-to-talk functionality (e.g., button) (204) which communicate with one or more base stations (206, 207) and a push-to-talk server (PTT server) (210). The system also includes a network connection (213) between the PTT service provider's network (208) and a public data network (215). The network (215) provides a connection to one or more unregistered network computers (217, 223, 224) with push-to-talk functionality (221), as well as a connection to a Directory Service (219). The Directory Service (DS) maintains a database of unique identifiers and associated push-to-talk addresses for the one or more unregistered computers (217, 223, 224). For simplicity, a direct network connection...

Abstract
A wireless phone user registered for push-to-talk (PTT) services desires a push-to-talk session with a party on a network computer accessible via a public data network (like the Internet) that is not registered with any PTT service. The registered user enters a unique identifier, as a destination address for such computer, and a PTT server uses the unique identifier to query a Directory Service available on the public data network to obtain a PTT address for the destination computer. The PTT server then forwards or proxies the PTT request to the destination computer. As a result, the number of push-to-talk destinations available to the wireless phone user is expanded to include any number of push-to-talk enabled computers available on the Internet that are known to the Directory Service.
