Indeed. In my case I do not care anyway. I have to use sip: as the gateway does not support TLS :-)
This is not entire true. A request can contain a RURI with sips schema even if it's sent via UDP or TCP (for example there could be a topmost Route with sip scheme). It's also valid in the case of a registrar which receives a request for an AoR with sips and must inspect in the registration backend for such AoR, no matter it's registered with a sip or sips address.
