RFC 3398 says that the mapping code for "480" is "18 No user responding": http://tools.ietf.org/html/rfc3398#section-8.2.6.1 This produces the caller see in its mobile screen "user not responding". I don't know if it's much better of my "502" -> "38 Network out of order" > Try it out, maybe the caller provider then plays a more correct early media > message (like "The number you have dialed is currently not available"). In fact I don't want the caller provider says early media, it should say nothing since it will be my provider who will say the early media. BTW, replying a "480" doesn't produce an early media in the caller provider, that is good. > If not, maybe you can answer with 486 Busy after you have played your own > early media message.

About replying a 403, yes, it could be, but again I don't know if it's better than the "480 or 502".
