Patent ID: 8150450

Claim:
A conference server, comprising: a first interface communicatively coupled to a first external radio adapter within a first radio network including a first group of two or more two-way radio devices, the first external radio adapter being physically connected to a first coupled two-way radio device of the two-way radio devices within the first group; a second interface communicatively coupled to a second external radio adapter within a second radio network including a second group of two or more two-way radio devices, the second external radio adapter being physically connected to a second coupled two-way radio device of the two-way radio devices within the second group; a conference room operable to manage a conference call between said two-way radio devices of said first group and said second group by receiving, at any given time, voice streams originated by one of said two-way radio devices of said first group via said first external radio adapter and said first interface and one of said two-way radio devices of said second group via said second external radio adapter and said second interface and transmitting said voice streams received from said first external radio adapter via said first interface to said second external radio adapter via said second interface for transmission by said second external radio adapter to said two-way radio devices within said second group via said second coupled two-way radio device and said voice streams received from said second external radio adapter via said second interface to said first external radio adapter via said first interface for transmission by said first external radio adapter to said two-way radio devices within said first group via said first coupled two-way radio device; processing circuitry operable to create said conference room for said conference call and communicatively coupled to said conference room, said first interface and said second interface to transmit, receive and process said voice streams managed by said conference room during said conference call; and an application program interface communicatively coupled to receive an instruction to create said conference room.
