Oh I was only saying it will be passed through much of the time - not that it will "work". There appear to be many Gateways, PBX's, and endpoints which can't handle media lines they don't support/understand. (ie, they reject the call instead of setting the port to 0 in the SDP answer) So some operators configure their SBC's to remove unknown types.
It's kind of sad, really.
