I'm not clear how you can get a PBX SIP CONNECT approved. A lot of the

a product could present a roadblock that prevents SIP CONNECT compliance
in a working setup, but I doubt that many products would do that.

Characterising the SIP forum as a who's who of retarded SIP providers
and PBXes is a little unfair. Practically everyone in the VoIP business
is in that list. Capability certainly doesn't look like a prerequisite,
though. :-\

Hehe, true enough. Perhaps I was a little harsh. Still, you are quite right about the compliance test being incredibly subjective and capability not being a prerequisite. Sonus and ShoreTel are not exactly known for their SIP interop features.
