Introducing Cisco Small Business Analog Telephone Adapters ATA Software Features 1 Feature Description Signaling Hook Flash Event The ATA device can signal hook flash events to the remote party on a connected call. This feature can be used to provide advanced mid-call services with third-party-callcontrol. Depending on the features that the service provider offers using third-party-call-control, the following ATA features may be disabled to correctly signal a hookflash event to the softswitch: • Call Waiting Service (parameter call waiting serv set in the Line tab) • Three Way Conference Service (parameter three-way conf serv set in the Line tab) • Three Way Call Service (parameter three-way call serv set in the Line tab) You can configure the length of time allowed for detection of a hook flash using the Hook Flash Timer parameter on the Regional tab of the administration web server. See "ATA Voice Field Reference," on page 115. Configurable Dial Plan with Interdigit Timers The ATA device has three configurable interdigit timers: Initial timeout (T)-Signals that the handset is off the hook and that no digit has been pressed yet. Long timeout (L)-Signals the end of a dial string; that is, no more digits are expected. Short timeout (S)-Used between digits; that is after a digit is pressed a short timeout prevents the digit from being recognized a second time. See "Configuring Dial Plans," on page 61 for more information. Polarity Control The ATA device allows the polarity to be set when a call is connected and when a call is disconnected. This feature is required to support some pay phone system and answering machines. Polarity Control is configured in the Line and PSTN Line tabs. See "ATA Voice Field Reference," on page 115.
