Summary:                    Asterisk does not retry a call on receving a 3XX
response
Description: 
Asterisk seems to be failing to retry a SIP INVITE when it receives a 3XX
response. I've tried this with promiscredir=yes and promiscredir=no but to
no avail. Both debug logs are attached. If I'm missing something in the
config to get this working, pls shed some light.

According to RFC 3261, a UAS SHOULD retry the call when it receives a 301
or 302 response. However, it's a MUST for a 305 response. Below is a
relevant quote from RFC 3261:

21.3.4 305 Use Proxy

   The requested resource MUST be accessed through the proxy given by
   the Contact field.  The Contact field gives the URI of the proxy.
   The recipient is expected to repeat this single request via the
   proxy.  305 (Use Proxy) responses MUST only be generated by UASs.

What we mutually agreed upon is that 305 handling is a feature request. The
302 handling is not a feature request because Asterisk supports it but
currently it seems to be broken. That would fall in the bug category.

Barring any config errors in my setup or that of the reporter of 10828,
the Asterisk is not redirecting the INVITE to the Contact address provided
in a 302 response.
