at quick check, the comment says the cseq is taken from the request
because it is processing the reply in this part of the code.
You change that to take the value of the stored cseq for callee, which
is different than the current processed message.
What was the problem you discovered? Can you give an example to
understand this change?

I see tag is also allocated each time, isn't
it exposed to same issue?
You changed only cseq to reuse existing buffer or free the old one and
allocate a bigger one when needed.
Cheers,
