I am trying to receive faxes from our PRI via a Sangoma A101 Pri card using Fax for Asterisk.

Faxes work Fax Machine => ATA => Asterisk => ATA => Fax Machine
Faxes work Fax Machine => ATA => Asterisk => PRI Sangoma PSTN
Incoming Faxes fail after 1/2 page when they come from PSTN(Sangoma PRI Card) => Asterisk(Local)

The also fail the same PSTN => Asterisk => ATA => Fax Machine

Here is a transcript of one of the failed sessions.
