[hylafax-users] T.30 T2 timeout, expected signal not received

["Manuele" <manuele@xxxxxxxxxx>]

Hi, I have a problem receving fax.
Sometimes (specially with faxes with 20-30 pages), the connection is 
interrupted with this error: "T.30 T2 timeout, expected signal not 
received". I am using a US Robotics Ext 56K modem.
Here is the log:
