hello everyone.i do have my raspbx in my office and it runs a sip trunk with 5 DIDs. one of them is dedicated for faxing. i do use my gmail account with postfix as smarthost to send only. so all faxes get converted to pdf and send to the email address.
i would like to send faxes as well, by making use of email 2 fax feature. is there a guide on how to set it up?
