<DIV>hi,all</DIV>
<DIV>i have just set up asterisk 1.6.0.7 rc1 with spandsp 0.0.5 pre4 to ReceiveFAX, link to a E1 (DE410P) using dahdi</DIV>
<DIV>this can receive the fax from E1 successfully, but i see many error message in the log like this:</DIV>
<DIV><BR>[Mar 16 09:24:38] ERROR[23540] channel.c: ast_read() called with no recorded file descriptor.</DIV>
<DIV> </DIV>
<DIV>when i receive a 5 pages fax, i will see this error message over 200 lines.....</DIV>
<DIV> </DIV>
<DIV>it seems the channel.c try to call ast_read(), read some bytes from the channel but there is nothing ...</DIV>
<DIV>whether it's a loop to check data on the channel ?</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>and many times when reciving tax , the E1 card will down , all the channel get red alarm...</DIV>
<DIV> </DIV>
<DIV>[Mar 16 09:49:19] DEBUG[20928] chan_dahdi.c: Monitor doohicky got event Alarm on channel 2<BR>[Mar 16 09:49:19] WARNING[20928] chan_dahdi.c: Detected alarm on channel 2: Recovering</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>i then try asterisk 1.4.23.2 and agx-ast-addon , when using spandsp 0.0.5 and spandsp 0.0.6, like above , sometimes all E1 channel get red alarm when reciving fax....</DIV>
<DIV>but use spandsp 0.0.4 get no error...</DIV>
<DIV> </DIV>
<DIV>some one can tell me what version of asterisk and spandsp is the best version for fax???<BR></DIV>
<DIV>thanks a lot.</DIV><BR><BR><SPAN title="neteasefooter">
