Hi all Can anyone help. I have a Revelation 2+6 that has been working without problems for about 10 years. For some reason the system appears to have reset itself. I can obtain an outside line by pressing the line key on the master phone, but when I dial 9, all I get is the engaged tone. I have checked that all extensions are enabled and that the exchange line is presented to extensions, I have also checked config code 50 all lines both incoming and outgoing, PABX access set to 9 on lines 1 and 2. But I just cannot get an outside line by pressing 9. Please help Thanks
