Push To Talk

PalmInfocenter.com: Orange Deploys Push To Talk With the Treo 600: "Over the last nine months, Orange has engaged in customer trials across Europe to develop and refine the commercial Talk Now� service, giving customers a new instant way of communicating alongside their existing voice and messaging services. It enables easy-to-access instant one-to-one and group calling with the added benefit of a real-time availability icon, so customers can see who is available to talk, and who is not. Customers can also create �team lists� that can be used to facilitate instant conference calling with up to 10 participants at any one time. Talk Now can also be switched to silent mode to ensure that people in the vicinity are not disturbed."
