    Interesting that he does not seem to quote a single example of one of these problems.

    Right, but they abound. For example, I’ve seen clients that (quite reasonably) tear down a call if they start getting media marked with a codec they didn’t negotiate. I’ve also seen poorly designed SIP/PSTN gateways that don’t negotitate comfort noise, but send it anyway. The results of attempting to interoperate between these two implementations are somewhat less than satisfactory.
