David Woolley commented on ASTERISK-21864:
------------------------------------------

This is a SIP problem, so, if it is repeatable, you need to provide the SIP debugging info specified for SIP problems.

ast_queue_control has been called for a source change, but with a null channel pointer.  It looks like it is handling an ACK at the time, so this is probably late offer SDP.  The call is from chan_sip's handle_incoming function.
