Re: [hylafax-users] failure to receive silence

Hi Yannis.

You will have very limited success with the Smart Link modems when used for
fax.  If you are deploying this solution in quantity you might want a fax
board from a company who are developing and supporting new fax products;

Subject: Re: [hylafax-users] failure to receive silence



Lukasz, Lee, thanks for the suggestions. I tried it out and now I'm getting
a "No receiver protocol (T.30 T1 timeout)" error (see log below). I also
tried sending the fax using an external Smart Link USB modem (driver slusb)
and the fax went through without problems. So the error I'm getting has to
do with the internal PCI modem. Is there any other configuration option I
could try?

We'd much rather use an internal PCI modem than an external one, are there
any suggestions? Which internal PCI modems are known to work well with
hylafax for production environments? Since we will need to order large
quantities, the lower the price the better.

Here is the new log:
