  • Calling number identification function
  • The FXO analog voice gateway can be connected to the fixed line of a telecommunication operator or an extension of an analog switch. When the external line is activated, the gateway can automatically detect and identify the calling number and send it to the docking server. Mainly supports 2 kinds of caller ID formats:
  • DTMF (DualTone MultiFrequency);
  • Frequency-shift keying; FSK (Frequency-shift keying);
