Maybe, but that doesn't mean the concept is flawed. It should be possible to do it correctly. > Have you tried to simply disable it? Yes, the customer has tried that, but since NAT is involved, the lack of SDP rewriting means that the media streams do not get routed correctly. But I am specifically looking for people with experience of this particular product, rather than for general advice, as I am seeking support for my assertion that it has a specific bug that the vendor needs to acknowledge and fix.
