But, as Cullen has another opinion I don't want to waste time on arguing about that - and I am fully aware what 3264 says about receiving media before the SDP answer :)

In fairness here we have some different type of deployments environments. Christer is often concerned about an environment where using SIP, things like PRACK are used which allows one to get an answer before media. IN fact media is probably gated and won't work if there is not an answer before the media. I am often concerned about deployments environments where PRACK is not supported but media is not gated.
