SMX/CSM/USM : target-refresh-request from new IP
Hello,
I read in the documentation that the SMX/USM/CSM support the target-refresh-request as per RFC 3261 and 6141.
It is not clear to me if the SMX accepts a re-INVITE coming from an IP address which is different from the one used to register and to send the initial INVITE, being the terminal on a public access interface.
I mean that the typical re-INVITE scenario is:
A (from IPaddr 1) REGISTERs to the SMX.
A (from IPaddr 1) INVITEs B.
A receives 200 OK and call is up.
A (from IPaddr 1) re-INVITEs B with a new IPaddr 2 in the SDP.
while I don't understand if it is legal that:
