    Alcatel launches its own flavour of push-to-talk


    Alcatel has joined the push-to-talk (PTT) fray with the launch of its own PTT solution.

    Alcatel says its version can run on a wide variety of handsets already commercialized and equipped with this function, thanks to client software enabling interoperability with most of the devices on the market. The system is based on SIP (Session Initiation Protocol) for signalling and RTP (Real Time Transport) for voice broadcasting, following the early specifications of the OMA (Open Mobile Alliance) and uses the capabilities of the IMS (IP Multimedia Sub-system) as specified by 3GPP.
    Using Alcatel’s Proxy Platform software architecture, the Push To Talk server runs on Intel Xeon processor servers, using Linux OS.
    “Push-To-Talk is a key service and a turning point in the mobile operators data strategy,” Jean-Michel Cornille, President of Alcatel’s mobile solutions activities, said. “The application gives operators an immediate revenue opportunity.”
