Hi Guys, I'm trying from an AWS EC2 to generate SIPP calls to a remote server also hosted on AWS EC2, the problem is that I only have one internal private IP to bind on with SIPP and can't rewrite the SIP headers with -i option to use my AWS EC2 public IP.
My remote server reject my INVITE with a 488 Not acceptable here because messages come from a public IP but SIP headers contain the internal IP that I was using to bind. AWS EC2 is doing a NAT 1:1 between the public IP and private IP but it's not possible to assign an ethernet interface with a public IP. Do you see a way to achieve it ? Thanks in advance for your help. Best Regards
