[Asterisk-Users] X100P Tone-based Supervisory Disconnect ?

[willy at yponeinc.com]

The X100P hangup problem is indeed pervasive.  My current
testbed has the X100P connecting to an FXS breakout of a
dual ISDN channel box.  Indeed, remote hangup is NOT
detected.  When I switched it to a POTS line, all the sudden
it seemed to work OK.  This is a serious limitation in some
scenarios however.  There was a response a few days ago
about recompiling [*] with some different options in the
driver (had to do with the same problem on a UK line).  When
this gets resolved, this would make for another fine wiki
addition.
Cheers,
WW
