Hi,

How would we create a new INVITE message with Replaces header?

Thanks,
Sam

Hence, the message may still be routed to the proxy 1, but there is no connection between the second IP address and the proxy 1. The message will be then lost. I would like to replace the proxy 1 with the proxy 2 address so that the message can reach the SIP end point.
