This appears to be the Orange info.

I don't know anything about the handset mentioned, even if it has PoC or if it's some strange Orange software that's used. They definitely don't support Nokia handsets just now, though.
OK, update on this... from a FAQ on the Treo handset:
Does the Treo 600 support the push-to-talk feature?
The Treo 600 currently does not support this feature. Push-to-talk is a walkie-talkie like feature made popular by Nextel. Other carriers have started shipping phones that support this feature as well. There are rumors that some developers are working to create software that will enable the Treo to integrate with this technology.
I'm gonna assume Orange have added their own software for this one.
