[Asterisk-Users] Cannot handle frames in 2 format

[Matthew Boehm]

Any ideas on this? This has always worked in the past until we got this 
new customer and his new fax machine.

Faxing from my machine works fine. But faxing from his gives this error. 
I can't imagine why his fax machine would be causing frame errors.
