I have a customer using mck/citel 6000. the stamp machine is connected to the fax machine telephone port. The fax works and there is dial tone at the stamp machine over my butt set. When I attempt to put postage in the stamp machine I get a C23 error which says modem error and no dial tone. Fax was not busy, stamp machine dials 9 to get out and have 2 second pause for dial tone. Any ideas.
