Re: [Asterisk-java-users] Hangup Detection

[Martin S. <ma...@be...>]

Hi Deric,

It sounds like you're overriding
org.asteriskjava.fastagi.internal.AgiChannelImpl. Is that correct?

If so, I think you've got a bad assumption -- the hangup() method you're
overriding should *not* be called on a hungup channel. It's a
helper-method to command the channel to hangup, so by calling it twice,
you're asking an already-hungup channel to hang up again.

You've mentioned that your getData() call is what hands you the first
exception. How soon before that do you check if the channel is up? I
would expect your getChannelStatus() to fail the same way your hangup()
fails, as they both send commands that won't go through.
