I am the most computer literate in the office so I have been volunteered to install and maintain the Partner II System. My problem is that I have set the fax on extension 27. Assigned Line 5 as the fax line. I can send faxes all day with no problem, but an inbound call to the fax line results in a ring on the inbound phone and no answer on the Partner System. Out bound the Line 5 light is red inbound no light goes on on the line 5 button. I have gone through all of the suggested steps in the manuals with no luck, The fax machine is an HP Laserjet 3200 (multifunction machine) it runs fine on a dedicated line. Any help would be much appreciated.
