Trixbox w/ DNS SRV records?

[Bill McGonigle]

Has anybody here implemented name to extension mapping with Trixbox,  
SIP, and DNS SRV records?

The idea is somebody places a SIP call to 'bill at bfccomputing.com' and  
it looks up the DNS SRV record, finds that my SIP server can be  
reached at librescu.bfccomputing.com:5060/udp and then [unknown goes  
here] 'bill' gets mapped to 'extension 101' and the call goes  
through.  I see no reason why phone numbers can't be relegated to the  
same class of information as IP addresses in this day and age, so I'm  
keen to make this work as 'the right thing to do', even though I  
suppose nobody will use it right away.

So, I'm curious as to how that unknown bit works.  My level of  
knowledge on the technology boils down to 'has a Trixbox server  
running and has played a bit with some asterisk config file tweaks',  
aka 'don't know much about asterisk'.  I've done some googling on  
this and found a couple configuration hints, but no howto's or even  
really a theory of operation.

Hints, advice, ideas, and sabots appreciated.

Thanks,
-Bill
