<DIV><FONT face=Arial size=2>Hello,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>We use a Junghanns.NET quad BRI card to connect an
analog fax to an ISDN public network.</FONT></DIV>
<DIV><FONT face=Arial size=2>Connections are :</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Analog fax ------<analog>--------- Siemens
Gigaset SX225 mini-PBX -------<ISDN>----------- Asterisk with 4 ports BRI
-------<ISDN>------ ISDN public network</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>We send faxes to many destination.</FONT></DIV>
<DIV><FONT face=Arial size=2>Everything runs OK except for one callee for which
transmission is sometimes interrupt in early stages.</FONT></DIV>
<DIV><FONT face=Arial size=2>The callee receives faxes from many callers and
everything runs OK except with faxes from us.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Roughly, 1 fax out of 5 is interrupted in early
stages of transmission : the callee fax prints a blank page with a single line
printed at the top with our name and fax number.</FONT></DIV>
<DIV><FONT face=Arial size=2>Fax log shows "Communication
interrupt".</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>My question : why would a fax transmission
sometimes fail ?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Regards</FONT></DIV></BODY></HTML>
