[hylafax-users] Hylafax comportation with high latency...
Hallo,
I would like to use hylafax with fastweb.
Fastweb is a Telco Company that gives mainly internet data connection over
fiberglass, but as a classic telco company permits to have a classic phone
line FXO mapped on their apparates so you can connect a standard phone that
is then converted in VOIP stream (they said that codec is u-law so lossless).
The very annoying problem is that you can have a call with about 1 second of
latency. This (I think) would really decrease Hylafax reliability.
What I have is that from the old installation of Hylafax where we had a
classic copper phone pair, and hylafax did its work very well, now we are
experiency the situation where transmit and receive faxes with hylafax is
very difficult, many tryies and many requeues.
Prartial transmits and partial receives.
Reports from hylafax say only:
Communication failure during Phase B/C
But having a look to a session log runtime, it's possible to see that at some
point transmission end while in a page and then after a timeout of 1min:20
seconds, hylafax resumes its state.
But stop transmission.
The only difference was the line: before we have a copper line, after a
fiberglass and VOIP.
Could it be a problem of high latency?
I've tryied with a standard fax machine (hp multifunction printer) and all
work well......
How can hylafax help me?
For convenience I've included a sample log. Note that at about 17:49:38 modem
stop writing data:
Sep 16 17:49:38.89: [ 4976]: <-- data [1026]
and then hylafax resumes with error:
