Summary:                    Patch that makes chan_sip check if the forward
domain is itself on a 302 response
Description: 
With promiscredir=yes in sip.conf, Asterisk assumes that *all* forwards are
non-local and attempts to send them out over the wire. If the domain is one
that Asterisk is configured to accept, the call comes back (hairpin) and
Asterisk changes it to a forward in an attempt to handle the hairpin.

This patch changes chan_sip to make it check if the domain is one that it
handles before blindly sending the forward out on the wire. If promiscredir
is set, it *is* a local domain, and either the domain has a context set or
the global variable FORWARD_CONTEXT is set, the forward is sent to
Local/user at context instead of SIP/user at domain.
