Kicking callers out of a conference line

There were three connections...

I hung up the first one listed to see if that would work...

So then there were two channels...

I dialed back into the extension with the weird noises and it was still there. I checked the channels again...

Dialed in again- Asterisk still has 2 participants in the call and it's playing that terrible sound still.

From the verbose output, it looks like I hung up a legitimate call on conference 2216, when I really wanted to fix 2223. Is there anything else I can try?

Ah ha, got it!

I dialed into the crazy conference line and turned the volume down to keep from going deaf :)

voip*CLI> meetme
Conf Num Parties Marked Activity Creation Locked
2223 0003 N/A 72:35:51 Static No
* Total number of MeetMe users: 3

When I had joined it said there were 2 users already in the conferences, even though there were no sip channels (didn't try iax or anything else)

voip*CLI> meetme kick 2223

... didn't work, but this did!

.... output trimmed ....

Which is weird because I was the "last" person to join the call. But as soon as I ran that, I started to hear the default hold music instead of the crazy noise.

Hopefully this helps someone else!

It's very difficult. They are actual people in China not spam robots. Because they are people they can answer any question that we usually use to filter spam robots. They use different IP addresses and many other tricks to avoid filtering. The only thing I could do is not allow new users to post for a set time period. But this is annoying to new forum users. And I have seen spammers that create accounts then wait a few months before posting so this does not always work.

I am working on a way to filter out theses spammers but it's not easy.
