i have a customer that wants to allow a fax machine call his main number with a automated attendant and get the fax call be connected to the fxs port on the uc320w. is there a configuration that allow the AA to detect the fax tones and automaticly transfer the call.
Inbound faxes are handled via a specific DID number and the inbound call routing rule. Per the inbound number the call is routed to the fxs port of the UC320W. It's doubtfull if the originating fax machine could continue to send fax tones while the call was transfered and and the inbound fax machine answered the call and started the training sequence.
