What is proprietary PBX Signaling ?
Most well known brands of PBX and Hybrid Key Systems have digital phones. These digital phones work by using digital signals to carry the voice and telephone commands. These digital signals are only compatible with the same manufacturer. These digital signals are not compatible with most equipment you might use to extend voice communications over IP or the Internet. In the past, the only solution to extend phones from your PBX to a remote location was to purchase another PBX or Hybrid Key System for that location. We now have solutions to solve this problem.
