In my case I would be using DNS round robin.  So a UA would only be
registering to one * server at a time.  So wouldn't in fact be an
active/passive?  


If not could I call the Asterisk Manager Interface from my java fastAGI
to grab the sip channel status on each server?  I have not use the
Manager interface before so I don't know how fast it is, but does this
sound like it would work? 


To answer a previous poster. My issue for me is high availability and
scalability.    

Thanks

Doug

Yes. The crux of the issue that you can't have two servers responsible 
for updating the same records in the table, and that you can't have two 
servers both expected to react to changes in those records on an 
instantaneous basis (which is why you can't share the table across two 
active servers and expect both of them to be aware of where the peers
are).

No. You have said that you want the _other_ servers to be aware of that 
phone's registration and be able to deliver calls to it directly. That 
will not work.

If you want the other servers to send calls to that phone through the 
server it registered with, then yes, that can easily be done.
