I am having a weird problem where I have some SIP channels which aren’t cleaning up properly.
The thing I find strange is that nothing shows in “core show channels”, as in there are 0 active channels, but when I do “sip show channels” i get a couple of ‘stuck’ channels. The output shows that the last message received was BYE, which would indicate to me that they should have cleaned up.

2 active SIP channelsWhen I look at the detail of one of the channels, it appears they have their “need destroy” flag set, but they weren’t ever destroyed.
