i am having alot of trouble trying to send and receive faxes, i have an HP officejet pro 8720, i sent a fax to the google voice number i am using as the fax number, my fax machine rings when i send the fax to it but the fax always fails.
i have set the fax speed to the slowest available and i also disabled ECM
any help is much appreciated, i am really trying not to use the OBIEXTRAS but i will turn to that if need be, i would just like to use my analog fax machine how i normally have been, thanks
