Hello, I would like to do the following. an INVITE msg need to be redirected to an available server. So when I get an INVITE, SER will respond with "Temporarily moved" and will provide the IP of the available destination. To be able to obtain this info, I have written a module that has an exported function that I can call from within the .cfg file. This function communicates with a TCP server and obtains the IP address of the next available destination. The TCP server maintains the status and load balance info of all the available destinations. I know that I can use rewritehost cmd from within the .cfg file and change the host IP and then call sl_reply() to redirect the INVITE. How do I change the IP info from within the function that I have written Hopefully I am making sense here. thanks, Jignesh Gandhi
