I'm trying to setup a fax server with a Trixbox box equipped with a B800P card.
Trixbox is linked via the BRI connection to a legacy Philips PBX ( NT <----> TE ), not directly to the pstn.
With this scenario, voicemail is working without issues, the voice is recorded and then e-mailed to the relative extension mailbox.
When we try to send a fax, Trixbox is not able to recognize the fax tones and so voicemail-prompt starts, generating an error in the sending fax machine.
