I don't receive fax with hylafax + iaxmodem

Hi,
I have asterisk 1.6 on Centos 5.5 with hylafax 6.0.4 and iaxmodem.
The problem is that I can send fax but not receive. Then I think that is a problem of faxgetty.
This is the log of asterisk cli when I think to send fax myself.

I’ve reinstalled hylafax. Now, whene I call a fax number I can listen fax tone after 3 rings.
This is the log:

== Using SIP RTP CoS mark 5 -- Executing [<my_number>@incoming:1] NoOp("SIP/eutelia_fisso-0000001a", "estensione: <my_number>") in new stack -- Executing [<my_number>@incoming:2] Dial("SIP/eutelia_fisso-0000001a", "IAX2/iaxmodem") in new stack -- Called iaxmodem -- Call accepted by 127.0.0.1 (format ulaw) -- Format for call is ulaw -- IAX2/iaxmodem-3327 is ringing -- IAX2/iaxmodem-3327 answered SIP/eutelia_fisso-0000001a -- Hungup 'IAX2/iaxmodem-3327' == Spawn extension (incoming, <my_number>, 2) exited non-zero on 'SIP/eutelia_fisso-0000001a'
On the contrary, when I send a fax to myself I get this log repeatedly:

Then i get the error “no answer from remote”.
What can be?
Thanks.

Now, I tried to send a fax to my server asterisk and I received this answer:
NOTICE[2970] chan_sip.c: No compatible codecs, not accepting this offer!
Seems everything is correct because iaxmodem answer, but after I get that error.

I don’t expect you to be able to fax yourself like this (based on past trial and error).

Have you tried an analog fax to this box? I would remove any other variables that could be problematic, such as FoIP or anything that is not a true analog fax in this case…

Also what does “iax2 show peers” show?

Thanks,
