Since this is Fax for Asterisk, volume is not really an issue, since I only have four licenses on a brand new CentOS box (HP DL360 G6(or whatever is currently shipping from HP). Based on caller ID, it is not one caller inflating the numbers. Generally, a failed fax will succeed on a subsequent try. Previously, we were terminating faxes to a quad port Digium PRI card, everything from the OS to the hardware were from 2006. Although, I do not have exact numbers, they were much better from this "Unsupported" Digium setup over this "Supported" and sold for profit solution. Maybe there is a simple setting somewhere, but "RTFM" from Digium tech support when the FM offers no suggestion on how to possibly tweak settings for better success. Thanks, Steve Totarao
