When "minnie" responds with the OK "mikymouse can read the "minnie"'s private IP address from the Contact header Contact: <sip:[EMAIL PROTECTED]> When "mikymouse" has to send an ACK or a BYE he uses: ACK [EMAIL PROTECTED] .... or BYE [EMAIL PROTECTED] .... Can he use the private IP Addres ? i.e. ACK [EMAIL PROTECTED] ..... or BYE [EMAIL PROTECTED] .... A proxy can reject a sip message that contains the private IP Addres?
