----------------------------------------------------------------

One of these days I will learn how to follow the rules. Log attached to the issue.
In this test case, 103 is in an echo test. 101 dials *53102 to spy on 102, but 102 is not in any active channel and it spys on 103.

You will see a line in there like this.
{noformat}ast_verb(2, "%s ______________________ %s\n", ast_channel_name(chan), ast_channel_name(autochan->chan));{noformat}
The iterator for autochan is somehow grabbing a channel from another extension. It is as if Asterisk is just returning all active channels in the system rather than finding the ones that correspond with the extension. Of which there are none because the extension being spied on doesn't have any channels open.

> I have three extensions: 101, 102, 103.
> If 103 is in a call and I use ExtenSpy from extension 101 spy on extension 102 which has no active channels, it will spy on extension 103.
> {noformat}exten => _*52.,1,ExtenSpy(${EXTEN:3},qS)
> exten => _*53.,1,ExtenSpy(${EXTEN:3},qSw)
> exten => _*54.,1,ExtenSpy(${EXTEN:3},qSB){noformat}
> I inserted a debug statement into 'for (autochan = next_channel(iter, chan);' in common_exec() in apps/app_chanspy.c and see ast_channel_name(autochan->chan) is equal to the 103 channel.
> I would expect that the iterator object should be null since there are no channels for the extension.
> iter = ast_channel_iterator_by_exten_new(exten, context);
