Summary:                    [patch] When matching peers check invite from domain
against domain list
Description: 
In trying to get the Exchange UM play on phone feature to work I developed
this patch. Exchange UM is sending the below SIP invite. Asterisk ignores
the domain when finding a matching SIP peer based on username. Since the
invite from field matches a device in sip.conf with a secret Asterisk is
responding with unauthorized. What I needed was for Asterisk to IP match my
sip peer with insecure=port,invite.

INVITE sip:2001 at voip.mydomain.net;user=phone SIP/2.0
FROM:
""<sip:2001 at exch.testdev.local;user=phone>;epid=079E8F8013;tag=849256682
TO: <sip:2001 at voip.mydomain.net;user=phone>

The debug output looks like 

Using INVITE request as basis request -
5c97e0f0-5456-4b82-a7f4-e7f2adeba338
Found peer '2001' for '2001' from 10.10.1.31:19219

The patch address the issue by checking the from domain when domain
support is enabled. In my configuration I just needed to enable
autodomain=yes in sip.conf.

Now the debug output looks like

Using INVITE request as basis request -
54d10d2e-01d1-451e-b21a-ef4bba987a0f
Unknown peer from domain exch.testdev.local
Found peer 'exchange-vm' for '2001' from 10.10.1.31:37810

For those not utilizing domain support this will have no effect. In my
testing with Polycom and Linksys phones all setup the invite with From:
userid at registrationserver.

The From: header is not related to local domains. You register to an AOR in
a domain, which is given in the To: header. The r-uri can be the registrar
server or the domain you are registering in.

This patch is basically wrong, as it is against the RFC 3261 standard.
