Summary:                    Asterisk doesn't free udp ports
Description: 
I've had this problem on 1.4.26 also.
I've recently upgraded to 1.6.0.17 and problem also exists here.
Concurrent number of calls is usually not more than 25. All calls are SIP
to SIP. 

Number of udp ports used by asterisk is growing. For example at the moment
of writing this note:
34 active channels
17 active calls
1871 calls processed

Total number of udp ports open  - 1023

At the other moment it could be a little bit lower but anyway it is
growing.

There are many queues and different ivrs on the server. We also use AMI
for originating calls for our CC. 
I've noticed that asterisk writes warnings to log, for example:
WARNING[26372] chan_sip.c: Trying to destroy
"6009EE42DD5A4BDA81A18571C82B76310x0ad20c43", not found in dialog list?!?!
I don't know if it's related or not.

Please help me to debug this problem.

Sorry if I've chosen the wrong category.

---------------------------------------------------------------------- 
Output of "sip show channels" is usual (I've uploaded it). 
I will try narrowing this problem during weekend and night when the server
isn't busy by making different calls. I will post the results next week.
As for now it's quite hard to post something from console output or sip
debug because it is huge.
