Summary:                    asterisk is not closing unused RTP ports
Description: 
i am using asterisk in a production-enviroment with 200+ concurrent calls.
Also a TC400B transcoding card from digium is installed. 
the issue i am seeing: asterisk is not closing the open files/used RTP
ports. So after 2 days all the ports(rtp.conf) or all the file (ulimit -n
32768) are full.
To give u an idea, please see the number of open ports, open files and
active sip dialogs, right now.

# netstat -tunap | grep asterisk | wc -l
# 21348

# ls -l /proc/<asterisk-pid>/fd | wc -l 
# 21392

*CLI> sip show channels
...
109 active SIP dialogs

Unfortunately the patch is not working for 1.6.1.18

I've just checked on a server where no more calls are active since 1-2
hours and there are lots of UPD ports tsill open: (extract from netstat
-a)
