Hey List-  I have a fresh FS install on Centos 5.  I am trying to use the limit_hash application to screen caller ID numbers before transferring calls to another call server on my  internal network.

<action application="limit_hash" data="cidlimit ${caller_id_number} 50/1" />

<action application="transfer" data="sip/sofia/192.168.15.2" />

Is this the correct/best way to transfer all calls to another SIP server that will be managing all calls? Where is the best place to put this application so that it will run on every incoming call from several SIP providers?  I have installed all the sample data, and have several phones registered to extensions that can make internal calls.  I am just looking for the general outline of where these applications should go after I have setup the several SIP gateways for my external providers.  I am still noo and would greatly appreciate any advice as to the best way to configure FS to simply receive all calls from the outside, run the limit_hash, then transfer to another SIP server.  Thanks List!
