Viking Electronics’ E-32 is a vandal-resistant single button call box providing hands-free, two-way communication for a variety of applications. The E-32 is phone line powered and connects directly to a standard C.O. line, PABX extension/station or FXS port. The built-in dialer will cycle through five pre-programmed phone numbers when the call button is pressed. Phone number entries are stored in non-volatile memory and can be: cell phone numbers, PBX extensions and customer service call centers. The E-32 is equipped with intelligent call progress detection for automatic CPC disconnect and call rollover on ring-no-answer and busy tones. It can also be programmed to auto-answer an incoming call for effortless monitoring.
