I have an HP3200 multi-function printer in the office. I have a fax line coming in as CO5. The extension 27 is set up as the fax extension. The fax machine does not answer any calls on the extension, however it has no problem dialing out to send a fax. I have played with number of rngs, special rings etc. all to no avail. The extension works normally with a system phone connected. This is a Partner II Rel 3.1 system. I want the fax to go through the system so that we have the Fax trunk as an extra outbound line. ANy suggestons?
