I'll show here a simple picture showing U for what purpose WE need a gain control in THE modem.
Hylafax -> iaxmodem1 -> (*) - app_rxfax.
It doesn't work, cause app_rxfax has no idea about FaxTone....it's too light to hear.
Thus, between all of parties getting involved into such a mess (I mean fax receiving) I need some amplifier. Can it be an iaxmodem? I think it must be.

As I said the problem is in app_rxfax, it's too sensitive to voice gain. When transmitting fax to another IAXmodem everything is fine. U know that that app is very-very dumb&^%, so i thought that IAXmodem can became more flexible than it is now.

Please try using uLaw and see if that makes a difference.
I've seen other people with problems of iaxmodem audio being too-faint. However, the curious thing is that the audio coming from iaxmodem itself is not faint. Something else is quieting the audio, and I'm suspicious that maybe it is Asterisk when handling slinear.

I've tried both 711's. Buttttt...

....i have "transcode_via_sln = yes" in asterisk.conf ...it can be an option.
Thnx, but I think that THE modem will be more "interresting" with "amplifier" only for that reason i've openned a discussion.

I do understand that you have resolved to a solution of creating an audio amplifier from within iaxmodem. Please realize that I, too, must become convinced of this. So, please entertain some more intrigue.
Please show me the HylaFAX session log and also the rxfax log when you send a fax from HylaFAX/iaxmodem to the rxfax app.
Thanks.

You snipped the session log, and so I really need you to put the whole thing here.
