Summary:                    Asterisk doesn't add Route headers in NOTIFY when
the SUBSCRIBE came from a proxy
Description: 
Client ---- Proxy ---- Asterisk

The Client sends a SUBSCRIBE (Event: dialog) and the Proxy routes it to
Asterisk adding "Record-Route" header.

The correct behaviour would be:
1) Client sends SUBSCRIBE to Proxy
2) Proxy routes SUBSCRIBE to Asterisk adding Record-Route
3) Asterisk replies 200 and mirrors Record-Route in the reply (correct)
4) Proxy routes teh 200 to the Client
5) Asterisk sends an in-dialog NOTIFY containing a Route header (with the
value of the received Record-Route).
6) The proxy routes the NOTIFY to the client.

But Asterisk fails in step 5 since the NOTIFY generated by Asterisk
doesn't contain a Route header.

Of course, that NOTIFY MUST contain a Route header since it's in fact an
in-dialog request, and the dialog was created using loose_route (the
request forming the dialog, the SUBSCRIBE, had Record-Route inserted by the
proxy).

I've applied it it 1.4.23.2 and seems to work. I will check it properly and
tell here the result.

Thanks a lot!
