[asterisk-dev] Bug in chan_sip

[Jon Bonilla (Manwe)]

Hi there


I was reading the changelog of the new Asterisk 1.4.23RC and found this:

* channels/chan_sip.c: We don't handle 4XX responses to BYE well.
According to section 15 of RFC 3261, we should terminate a dialog if we receive
a 481 or 408 in response to our BYE. Since I am aware of at least one phone
manufacturer who may sometimes send a 404 as well, I am being liberal and
saying that any 4XX response to a BYE should result in a terminated dialog. 
(closes issue #12994) Reported by: pabelanger

AST-129


I guess that having only ip-phones in mind is not a good approach. Since it is
possible to have a sip proxy connected to asterisk we could receive a 407
(unauthorized) or 483 (too many hops) as response and dialog ending would not be
a good behavior.

Sould we reopen the bug or create a new one?
