Autoqos interoperability with Mitel?

Will the Autoqos commands work, even when Cisco gear isn't being used (Mitel, specifically).
I know that Mitel will use RTP for its voice traffic, but I'm not so sure about signaling/control protocols.
Anyone know about this?

I'm trying to set up the simplest QoS possible -- Just tagging data as it goes out. What would be the best way to accomplish that?
