Just following up on this - I can confirm Drew's information about the
unreliability of faxing through an Asterisk box.

It seems that anything above 7 or so pages will have problems.  I had
someone I know run some tests in a clean environment - no luck sending
anything above 10 pages in one try.  This is using G711u with a quiet
network.  It just doesn't work.

Not nice, but good to know.

Regards,
Dave.

 There is a current thread on asterisk-users "Fax Blast over IP?" that may

support it we say yes and no.. and then explain that they can use it.. and
fax away all they want, but if they have issues we don't support it. "

The conclusion seemed to be that it will generally work fax m/c --> ATA
--> Asterisk --> PSTN but only if you use the G711u codec. You need a good
network path (LAN with no congestion).

Lifetime Guarantee ;- When it breaks, it's end-of-life.

If one does decide to go with an ATA, does anyone have any suggestions
about which ATA works best with faxing?
