[Kamailio-Users] Question about force_send_socket() as it relates to record_route()

I am not sure that answered my original question, but perhaps that
leads me into my next idea of how to accomplish this.

If I have a kamailio server bound to two IPs

If the server receives an INVITE on and I use LCR to forward
it out, will the IP kamailio sends FROM be the same it was received

If so, I can simply configure my Asterisk servers to send to different
IPs based on the type of traffic.


p.s. I think you already answered this, but I just want to be 100% sure :)
