<p>Hi Tim,</p>
<p>Unfortunately i can't reproduce the scenario because it was a long time ago. But it would be nice to hear from you, what things can be verified within fax and Asterisk? Any TIP on wireshark monitoring?</p>

If Asterisk was freezing up, that would seem to indicate a problem with Asterisk, not the Hylafax/IAXmodem components. Of course, details would be needed to determine why that was the case.<br>
<br>
Regardless, without lockups of Asterisk, reliability of fax is very dependent on timing and audio quality. Again, details would be needed to further investigate why you had high failure metrics(specifically your fax session logs from /var/spool/hylafax/log).<br>
<br>
In general, Hylafax+[1] and IAXmodem is the most rock solid stable fax solution available, as long as you can get past the initial learning curve. There is a reason why IAXmodem has not had a release in forever as the 1.2.0 release is rock solid stable. Hylafax+ continues to be developed with regular releases, the feature set and functionality are second to none with hooks for almost any imaginable configuration, and the support via the mailing lists or available contractors can't be beat.<br>

If you have specifics about your problems with Hylafax and IAXmodem, I'd love to hear about them to help diagnose, if it is postmortem.<br>
