[asterisk-users] Force hangup not working on stuck channel

[Carlos Chavez]

I am unable to force a hangup on a channel that has been stuck for over 
two days:

IAX2/from-CD-11006   oficina              2770                1 Up      
Dial         IAX2/to-CD/2883           3467130007      46:24:59 Sotelo   
    Sotelo      IAX2/to-CD-20713

I have tried "hangup request IAX2/from-CD-11006" several times but no 
joy.  I also see the following in the CLI:

[Nov  3 10:05:54] WARNING[2879]: chan_iax2.c:4936 handle_call_token: Too 
much delay in IAX2 calltoken timestamp from address X.X.X.X

This is an IAX2 trunk between two Asterisk 1.8 servers (I know it is old 
but new client so haven't had time yet to upgrade to 13).  Because this 
channels is stuck
  all other calls between servers are not working.  The only way I have 
found to resolve the problem is to stop and restart Asterisk.  This is 
obviously a great inconvinience so is there a way for force iax to 
unload even if there are channels in use?  Or any other way to kill 
these stubborn channels?
