Hi, I asked a similar question couple of months back and got a satisfactory answer. So here's the answer to your question. What it will do with such an INVITE depends on the UA, it's configuration and capabilities. For e.g. it may be a Fax terminal, or an IVR, which doesn't necessarily require a user-name.
