I just recently migrated from Unity 4.0.5 to Unity 8. I know that Unity IP Fax isn't supported in v8 however I do have it working with one exception. I cannot get the software to render PDF files on outbound faxes. On Unity 4 I installed Adobe Reader 7. On Unity 8 I install Adobe Reader 9.3.3.
I have added the PDF file extension to the 3rd party fax admin in the tools depot and selected "Cisco Unity IP Fax Routing" as the fax server. Basically I have configured everything the same in v8 as it was in v4.
Does anyone else do this? Any thoughts?
