T.37 Fax Problem - Lossing end of pages

Good Evening,

I have configued UC520 to receive faxs and forward them on to our e-mail server.
The issue I am hitting is that the end of most pages are missing.
My inbound trunk are two ISDN BRIs with DID.
Below is the config from the UC520. Any ideas what is missing or where to start looking?

Thank You.
