  • Transparent call progress
    Patent number: 6055443
    Abstract: A cellular modem pool provides call progress information to a calling party during call setup. In particular, the cellular modem pool includes a coupling means, which communicates any signals between the cellular-side of the cellular data connection and the PSTN-side of the cellular data connection during call setup. This allows the calling party to hear the call progress on the called party side of the data call. In addition, the cellular modem pool monitors the signals for a data signal provided by the called party, e.g., a predefined answer tone. Once the answer tone is detected, the cellular modem pool opens the connection provided by the coupling means and processes the respective signals on the cellular-side and the PSTN-side of the cellular modem pool.
