[Asterisk-java-users] LinkEvent clarification

[Alex M. <al...@go...>]

In the documentation for LinkEvent there's a note that it is possible to
receive multiple LinkEvents for a call. This is ok. But is it guaranteed
that for each channel receiving a LinkEvent there will be a
corresponding UnlinkEvent? In other words, is there any possibility that
code like the following could cause the openCalls Vector to have a 'left
over' channel name? (Assuming that a channel switching between being
Channel1 and Channel2 isn't an issue.)

openCalls.add(linkEvent.getChannel1());
...
openCalls.remove(unlinkEvent.getChannel1());

To answer your question I must look at the asterisk source code -
documentation of asterisks manager api is not that reliable yet ;)
I will check this next week when I am back.

I didn't find exact evidence that guarantees this behavior but if
Asterisk does not provide a corresponding UnlinkEvent i would consider
this a bug in Asterisk.
Actually i never observed a missing UnlinkEvent so i guess your code is
reasonably safe.
