    We updated to SP5 yesterday and now we can not receive faxes via 3cx.
    When I change the destination from a 3cx fax (8888) to a physical fax machine via "3cx Fax Extension" to GrandStream 704 it works fine.

    Interesting - any chance you want to tell me your provider or codecs in use or other settings - reinvites, replaces, etc...
