[reSIProcate] does sipstack send TransactionTerminated event when ACK transaction end?

["Roland Zheng" <rzheng@xxxxxxxxxxxxxxxxxxxx>]

ACK transaction is very special.

I am wondering if sipstack sends  TransactionTerminated to TU when the ACK transaction ended.

If so, what is the transactionid inside in TransactionTerminated message?

And how about other special method such as CANCEL?

Thanks,

Roland
