[Kamailio-Users] Sending from 1 of N ip address

I have a requirement from an upstream provider that is providing multiple termination only gateways to me. The requirement is that I have to have a unique source ip address for each gateway that I will be terminating calls to. I would like to use only one kamailio system bound to multiple ip addresses to meet this requirement. I have my LCR built with the various routes to the gateways. I have identified the function force_send_socket([proto:]address[:port]) which seems like it can be used to meet this functional requirement. I am a little confused how to implement this function with LCR. My basic requirement is that if upstream gateway ip address == 1.2.3.4 then originate and maintain the dialog from my source ip 4.3.2.1 else if gateway ip == 6.7.8.9 then originate and maintain dialog using soure ip 9.8.7.6, else if ... N upstream gateways Is force_send_socket([proto:]address[:port]) the function that I need to be trying to use to meet this requirement? Is there a simpler method that can be used instead? Any help will be appreciated. Stagg
