What version of HylaFAX are you using?

Are you submitting them all with the same time-to-send? Or are they all 
just going in with some reference to "now"?

My experience [and very recent testing] with HylaFAX+ 5.2.4 sending 
broadcast faxes to the same number using sendfax -z and referencing 
"now" in the time-to-send shows them all getting sent in the order in 
which they were submitted.

Thanks,

Lee.

_______________________________________________________________________

I am using HylaFAX 5.2.3 and submitting all of the faxes to go out
"now".
I am using the Perl module Fax::Hylafax::Client

I am attaching the pertinent log messages and would appreciate your
thoughts. One thing I noticed is that the COMMID is staying the same.
I do have MaxConcurrentCalls set to 20, is that whats messing me up?

If I had 8 lines outgoing and 10 lines incoming on the other side, would
it be fastest to set MaxConcurrentCalls = 1?


Looking back through my logs, it looks like that is what is happening.
All of the faxes to one number were queued up for the one line while the
fewer number of faxes went to the other, and since there was a line
available it sent newly submitted faxes out that line. I am including
this here in case anyone runs into this in the future.
