Hi Group
I have a couple of Asterisk systems that SIP channels are locking up periodically. In both cases they are experiencing some fairly significant network issues which is likely causing the issue as below:

Most peers showing ACK are locked channels.
Excerpt from sip show inuse

885 2/0/0 10
880 2/0/0 10
842 2/0/0 10
823 2/0/0 10
sip reload does not clear the channels.
So my questions are:
- Is it a bug that this is occurring?
- If not, is there something that I can do to make sure these channels clear?
- Could this have something to do with RTCP?
- How can I clear the channels without restarting Asterisk?
Thanks so much all.
