Re: [hylafax-users] failure to receive silence

[Ioannis Mavroidis <imavroid@xxxxxxxxx>]

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:
