What phone are you using? A GXP-2000 or other model? I received notice 
of someone experiencing a sporadic 'ring' on his phone, but I'm not sure 
it was after haning up a call..

Do you use CDR logging (to mysql?), if yes, do you find anything in 
there about this call?

Maybe try searching through the asterisk logfile for records of this call?


Cheers,
