Re: SIP error codes interpreted by Asterisk as?

Hi Olle,

The thing is, we use VoIP completely. All our systems are
over IP, and so we
have no T1, PRI, etc. 
So, accordingly, quite a few times when a call fails,
Asterisk seems to
classify it under 'reason 0'. Be it congestion, or
disconnected number, or
sometimes even a fast busy gets classified as reason 0.

I'm trying to remove disconnected numbers from our contact
lists so we can
actually get by through email or something. Either way, I
really want to
somehow figure out what the disconnected numbers are. And
with almost all
failed calls getting in the 'reason 0' category, it's hard.

Any suggestions would be greatly appreciated.

Thank you,
Mark.

I am at loss on how to answer, guess I don't really
understand the  
question.
We do translate from SIP2ISDN and from ISDN2SIP all the
time. When  
Asterisk
in itself the cause of the hangup or the disconnect, we've
tried to  
make it
as good as possible, but there's propably room for additions
and  
changes.
Feedback on the implementation is more than welcome, so that
we can add
proper hangupcauses and error codes in more parts of
Asterisk.
