Applies to version(s): v3.0
SBC/Tmedia can be configured for SIP messages traversing a remote NAT as follows:
- None: Remote device is not behind a NAT, or reports SIP headers (contact, via) that are directly reachable.
- Automatic N AT Traversal: Parse the Contact IP address of the packet and check if it corresponds to a private/reserved IP range. In that case, SIP messages will be sent to the IP/Port seen in the IP header rather than the SIP headers.
- Force Use of Public IP and Port: Use the IP and port from the IP header of the last received SIP packet.
