[hylafax-users] IAX Modem + Failure to receive silence (synchronization failure).

[Jeff <jeff824@xxxxxxxxx>]

Hi,

When ever I try to receive faxes it errors out with the error Failure to receive silence (synchronization failure). Any suggestions would be much appreciated, below are the log files and the config.ttyIAX for your reference.

Thanks, 
Jeff
