asterisk users - Jan 2004 - Identifying the Originating Cisco SIP Gateway

I have several Cisco SIP gateways sending calls to Asterisk.  Because the
gateways don't have user-agents, they don't authenticate with Asterisk. 
And
because they don't authenticate, they use the default context in the
sip.conf file.

Is there a way to either:
A) identify the inbound gateway with a variable, in channel info, or the
manager interface?  If there was a ${SIPDOMAIN} for the originator rather
than the destination, that would be cool, or 
B) make the inbound gateway use the sip.conf file section belonging to it
via the host= line in the sip.conf file without user authentication, or
C) some other way I have yet to fathom

I'm trying to differentiate between legitimate gateways that initiate calls
vs other gateways that should get a very limited inbound capability.

Last time I checked this, it worked as you want only if your SIP Gateways are 
on port 5060.  I was able to differentiate via the host=line, but as soon as 
I used a Gateway on a port other than 5060, Asterisk was not able to match 
the sip.conf entry and it used the default.   I did not open a bug report as 
this was not something we needed at the time.  Give it a try and let me know 
if you see the same thing.
