[Freeswitch-dev] trouble on how to remove the media bug from the session after the sessions are closed

Mon Oct 10 20:03:33 MSD 2011

 yes, I use the SWITCH_ABC_TYPE_CLOSE type and I've found the media bugs are automatically removed with the DEBUG log infomation. Now the problem is the session ending.

Detailed situation description: I added two media bugs to both local session and remote session of one call. When I ended the call, the media bugs are removed first, and then the session should be ended. But only the local session is ended correctly. 
When I press F3 and F4 to show current channels and calls, the remote channel and call info is till there. But when I try to dump uuid to get channel infomation with the cmd "uuid_dump remote_session_uuid", it says there is no such channel!

here is some related log info:

Could anyone give me some hints why the remote session is not ended automatically?
