Summary:                    "502 Bad Gateway" is translated as "NO ANSWER"
instead of "FAILED", why?
Description: 
Hi, IMHO it's clear that receiving a "502" from a SIP server means that
some kind of error has occurred:

  21.5.3 502 Bad Gateway
   The server, while acting as a gateway or proxy, received an invalid
   response from the downstream server it accessed in attempting to
   fulfill the request.

But Asterisk translates it into "NO ANSWER" instead of "FAILED":

  -- Got SIP response 502 "Bad Gateway" back from XXX.XXX.XXX.XXX
  == Everyone is busy/congested at this time (1:0/0/1)

And this originates a "disposition=NO ANSWER" entry in CDR.

I think HANGUPCAUSE 27 ("502 Bad Gateway") should be mapped to "FAILED"
call disposition instead of "NO ANSWER".

Regards.
