<p class=MsoNormal> <span
lang=EN-US>I’m having a strange problem with the IAX2 channel and
IAXmodem and I was hoping to get some light from someone in these lists.<o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-US> The
strangeness comes when I debug the iax2 channel (iax2 set debug): the events(missed
PONG I guess) that lead to the UNREACHABLE state don’t appear on the
console and on the log I get only 10% of the total state change messages I was
getting first. Disabling the debug, the lines reappear as before.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US> The
state is changed from UNREACHABLE to REACHABLE after 10 seconds(given by qualifyfreqnotok),
as documented above.<o:p></o:p></span></p>
