Does the call blocker work with Nec, Avaya, Northern Telcom, Panasonic and other brands of PBX?

The Call Blocker can work with these PBX systems if they are analog on the front end CO trunk inputs or through PBX configured analog phone ports. The Call Blocker will not work on digital Key Set lines from the PBX. However, you can ring a PBX configured analog phone port to the Call Blocker simultaneously with the Key Set phone and then control the inbound ringing.
