[hylafax-users] t38modem, failure to receive silence

[Daniele Martini <d.martini@xxxxxxx>]

Hi,

I'm using t38modem (0.8.0) with a cisco voice gateway

hylafax is version: 4.4.0-2 (shipped with ubuntu)

Sometimes i get an error "Failure to receive silence".

Those are some entry in my config.ttyx file:
ModemType:		Class1		# use class 1 interface
ModemFlowControl:	rtscts		# default
ModemRevQueryCmd:	AT+FREV?


T38modem and the cisco voice gateways are in the same LAN so I don't think
there is any problem of packet loss.

Can someone help me ? :)

Thank you.
