No need for POTS jacks. The VoIP Blasters have RJ-11 jacks on them. -----Original Message----- From: Chris Riddoch [mailto:socket at peakpeak.com] I believe there is an ethernet jack in the front of the room. I'm not sure if there's a phone plug for the POTS speakerphone for the VoIP demo, but there's probably one in the building.
