Call Threads waiting for with_next_message() hang indefinitely
Reported by Jay Phillips | August 29th, 2008 @ 02:12 AM
When a dialplan Thread is sleeping due to with_next_message(), a call hangup will NOT kill the Thread. The Thread stays alive for as long as the process does.
For the time being, this can be worked-around by manually catching hangups via AMI and sending a message to the dialplan which causes it to exit gracefully.
The framework-level solution I believe is to subclass the Queue class and use this custom subclass in for Call#inbox(). It will override the Queue#<<() method with an implementation that checks for the :cancel symbol and sets a property in the Queue subclass to disable any further use of with_next_message() by raising an exception. The :cancel message is still passed along to the Queue.
The documentation of with_next_message() (and its supporting methods) should mention that :cancel can be sent at any time.

This just has to check the socket connections status. When the GServer socket disconnects, it should just update the Call object and put its inbox into the "closed" state.
