[hylafax-users] excessive "delay 1500 ms" errors
I'm running a couple of hylafax servers and things are working
great for the most part. I'm using the t38modem.
I have noticed that for some inbound calls the fax never comes
though. It seems that the faxmodem answers but then the call gets
dropped after several seconds. In almost all cases I see a long
sequence of "DELAY 1500 ms" errors. I've pasted a complete log
file below for reference.
This seems to be isolated to particular callers since I am often
receiving "good" faxes at the same time that these bad ones are coming
in. I am seeing this behavior on both my fax servers.
What might the problem be? What can I do to try to fix
this.
