Hi Iskren,

What do you mean by 'true IP address'? The real IP address of a device which sends a request?

$si and $sp reference to the source IP address and port of the message, "Via" header contains IP address and port of UA and it could be different from $si, for example if UA is behind NAT device.

Hi list,

How can I reliably get the sender’s IP address?
$si and $sp are returning the server IP and Port.
I also tried using $Ri and $Rp but it yields the same results.
Inspecting the packet shows the sender’s true IP:Port pair in the Via: header,
but the From: and To: contain the kamailio server’s public IP address.

Kind regards,
