i played with sbc module and noticed that when calling party cancels
invite after 180 ringing, i get to syslog error message about the ack
that sems receives after sending 487 response:
May 6 15:55:16 sip sems[25920]: [#b59fab70] [handleSipMsg,
AmSipDispatcher.cpp:81] ERROR: received ACK for non-existing dialog
([email protected];remote_tag=fdjbj;local_tag=35F7881B-4DC3EFB30001EE20-B59FAB70)
when i compare callid and the tags of the ack to those that sems
received in the invite, i see that they are the same.
any ideas why sems does not match the ack?
if you examine the log before that ERROR, you will see a line
DEBUG: ACK matched INVITE transaction
so the transaction was matched indeed.
it's just the ERROR message, which probably should be a DEBUG. I think
it is the same story as the unhandled reply to BYE - at that time on
dialog level SEMS already forgot about the call, as it really finished
processing all what was necessary/possible for it.
thanks for reporting, I will set that to DEBUG.
