Summary:                    Asterisk doesn't reply well to in-dialog OPTIONS in
pedantic mode
Description: 
A way to monitorize a SIP dialog is by sending in-dialog OPTIONS so the
UAC/UAS replies with 200 OK if that dialog exists or 404 if not.

Asterisk with pedantic=no replies a "404 Not Found" correctly but in
pedantic=yes it replies with a "481 Call/Transaction Does Not Exist".

I'm not 100% sure (I'll try to confirm it) but I think it should reply
with a 404 instead of 481 in this case (OPTIONS in-dialog).

Thanks. However, you only have the debug output here, I need it all -
verbose and the actual SIP messages too. Set verbose and debug to 5, turn
sip debug on and capture again. Sorry for the extra work.

I think the issue here is not the 404, because you propably don't have an
extension called "asterisk", it's that it causes the call to hang up on a
non-fatal in-dialog transaction. We are always requested to answer to
OPTIONs as if it was an INVITE, regardless if it's in-dialog or not.

I need to see more output though, before I start working on a patch and
try to fix this. Thanks for your patience.
