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

["MOLLE Thomas" <t.molle@xxxxxxxxxxx>]

OK, I'll try to receive with another fax. But I don't think that Hylafax or the modem is in cause because I have this problem only with some transmitter.
Try with another fax, will confirm that.

Thank you for your help

Thomas.

So here the Phase C image data carrier is detected, but after 3 seconds 
the carrier is lost.

Then HylaFAX goes to listen for the Phase D signal but it seems the 
sender is still transmitting the Phase C signals or the audio is very 
corrupt.

Then HylaFAX asks the sender to retransmit the Phase D signal, but then 
some more problems in receiving any signal.

And at this point it appears that the modem is on-hook.

It could be modem problems, it could be audio quality problems.  If you 
have a different modem model to test with it may be worth trying.

HylaFAX+ 5.4.2 (http://hylafax.sourceforge.net) would give you different 
behavior here at some parts, and it's possible that it would get 
slightly different results, but not likely.

Thanks,

Lee.
