Queue - Ghost channel not killed

Hello,

I’ve encoutered a curios behaviour, would like your thoughts about it.
I’m originating with files moved into /var/spool/asterisk/outgoing.

  1. from external number to internal sip phone
    Channel: SIP/Wengo/0388XXXXXX
    Context: from-internal
    Extension: 10

    This one works fine, external number is ringing then on answer the internal phone is ringing

  2. from external number to a queue (extension 13)
    Channel: SIP/Wengo/0388XXXXXX
    Context: from-internal
    Extension: 13

    Works fine as #1 except that when 0388XXXXXX hangup before an agent take the line, the channel SIP/Wengo-xxxx stay alive and the entrie queue too, even if 0388XXXXXX is gone.
    The agent registered in the queue keep on ringing, and the channel is correctly cleared only when the agent take the “ghost” call and hang it up.

Strange… Anybody has an idea?

Thanks

I have the same problem did you find a solution to this?
