Re: [hylafax-users] T.30 T2 Timeout (redux)

Update:
Was not using VOIP, I am using Centrex POTS lines. Had our lines checked
for noise. Came back clear. I decided to replace one of the modems. So I
bought a Multitech MT5634ZPX PCI internal modem.  Replaced the modem
that gets the most traffic and most errors. Not a single problem in the
3 days since I swapped to the new modem.

On a side note: 
I decided to open a support case with US Robotics.  They say they don't
support Linux or my modems because they are so old. 
To me they are alienating some of the only people (fax server users) who
would possibly buy their products!!  Not sure, why any company would
take that route, but anyway. Anyone who may be reading this I recommend
not wasting your time or money on 3com / US Robotics modems for faxing.
They don't work right all the time and have no support.

If you see this kind of thing happen frequently/regularly with many
different senders, including the many PPR signals, then it's a strong
indicator that the audio quality on your phone line is bad.  Have the
phone company take a look.  Don't use VoIP.  Make sure the sender isn't
using VoIP, either.

Thanks,

Lee.
