Have a Call Pilot 100 attached to a Nortel. Am using 3 digit extensions. The first one the supplier send didn't work so they sent me another. I can not configure it. They sent it to me pre-configured (for two digit extensions) I guess so they knew it worked since the first one didn't. Have tried to log on through my network and I can see the Call Pilot. Can ping it but get no other response. The IP address is correct. Any ideas?
