I tried to configure inbound FAX using IVR/Call Flow Builder. The key component is GOODIES which automatically distinguishes between FAX and regular calls - the former is routed to the RECEIVE FAX component while the latter follows the SIP/VOICEMAIL path. I received errors after saving/validating the call flow relating to missing connections but could not figure out how to resolve the issues. I used the 'Typical Small Business Call Flow with Fax and Auto Attendant' template and removed the components I did not need. Although this call flow also did not validate, I was able to both receive FAXes (I resurrected my old laptop with a built-in FAX modem) and handle regular calls. Both call flows validated today - no sure what changed.
I originally tried to test inbound FAX with
https://faxzero.com/ or
http://www.myfax.com/free/ - neither FAX arrived. FaxZero claimed "... failed due to poor connection with device or recipient fax macvhine maybe outdated and incompatible", MyFax was silent on the issue.
