IMPORTANT:
The VISITED station already gets the protocol
to be used for connecting to the HOME gateway from the SPE Mobile HFA
call flows.
| (1) | SPEcapable clients have to use TLS when acting as VISITED stations for a SECURE / CIPHER client. |
| (2) | This scenario is critical due to PIN and H.235 password transfer over insecure network links. |
| (3) | Secure/Cipher clients have to use TCP when acting as visited stations for a traditional client. |
| (4) | Secure/Cipher clients have to use TCP when acting as visited stations for a SPEcapable client. |
