[Asterisk-Users] Exception flag set on 'UniCall/2-1', but no exception handler

[Jose Chiantera]

Hi

When I make a call from the outside to asterisk and the call is asnwered, 
all is OK, but when I make a call from the outside to asterisk and hangup 
before the call is answered, you got this WARNING in the console:

Jul  6 19:33:08 WARNING[10037]: channel.c:1521 ast_read: Exception flag set
on 'UniCall/2-1', but no exception handler
Jul  6 19:33:08 WARNING[10037]: channel.c:1521 ast_read: Exception flag set
on 'UniCall/2-1', but no exception handler
.

Jul  6 19:33:08 WARNING[10037]: channel.c:1521 ast_read: Exception flag set

and the warning has repeted and the extension ringing forever, until
you offhook the extension or stop de asterisk
