[hylafax-users] Failed faxes when using class 1.0 on mainpine

[John Warren <jwarren@xxxxxxxxxxxxx>]

For the last couple of months I've been running our systems with the modem set to class 1.0. I like the faster speeds but I've been getting a fair number of failures that I don't see when running class 1. 

There seems to be a number of fax machines that don't like receiving from us when running class 1. 

I've also see problems where others can't send to us but we can send to them, again this only happens when running class 1.0. 

If I set sendfax to use 9600 bps for the one job the fax will still fail. 

Only changing to class 1 seems to fix the problem.

At the end of this message I've included parts of the transactions for one site I've had real problems with. Fax number change to be non-readable.

So, anyone have any ideas? I've just about run out of options.
