Well, you shouldn't. You should use transport=tcp, because that is the transport protocol you are using. That you want this encrypted is indicated by the sips scheme of your SIP URI.
It's like in HTTP world:
- http:// means HTTP over TCP. - https:// means HTTP over TLS over TCP.
Since HTTP just works over TCP, there is no reason for a ;transport param. But SIP protocol can work over different transport layers (TLS is not a transport layer).
