<DIV>Hello Eric,</DIV>
<DIV> </DIV>
<DIV>call progress detection is the problem. Asterisk mistakenly recognizes the
call to be answered and then still "hears" the ringing that should not be there
if the line was really up.</DIV>
<DIV> </DIV>
<DIV>To solve the problem you would have to either implement a progress
detection matching your country's indication tones or at least adjust the
existing one for US or Costa Rica in dsp.c.</DIV>
<DIV> </DIV>
<DIV>By the way on the "Read the damn docs." issue:</DIV>
<DIV>You could choose not to answer these questions. Anyone not getting an
answer here would possibly take a second look at the docs and find what he might
have overlooked.</DIV>
<DIV> </DIV>
<DIV>Regards</DIV>
<DIV>Tobias</DIV>

<BR>> Ring/Off-hook in strange state 6 on channel 2</DIV>
<DIV>> </DIV>
<DIV>> Does anyone have any idea what is causing this and how to fix
it? The <BR>> mailing list archives had lots of questions, but no
answers regarding <BR>> this error message.<BR></DIV></BODY></HTML>
