[Users] what is the in_network table for

[Brandon Price]

We have 1 asterisk and 1openser installation, with 1/2 of our users  
registering to one and 1/2 to the other. What I wanted to do for in  
network calling is add a column to in_network table thats called ip.  
In that column I want to put the ip address of the asterisk machine  
that the calls for those in network users that are registered to it  
should go. Then somehow set up openser to do a (lookup) then failing  
that look up the number in this database, if its rewritehost the call  
to ip in the ip column, else forward to our pstn gateway.

Has anyone done this before, how would one handle multiple openser  
installations with 1/2 of the end users registering to one and the  
other 1/2 registering to the other barring a shared userloc database?

What was the in_network table made for?

As always any help greatly appreciated.  Thank you.
