(Personally I think SIP desperately needs at least 20
additional
defined Response Codes so we can all quit using the existing
not-entirely-inappropriate values to cover real-life situations,
but right now the book says that's all the codes that we've all
got to work with. When you see a dozen SS7 release codes all
map to the same SIP Response Codes, you don't have nearly enough
SIP Response Codes, but I digress.)
There is a painful draft about the usage of 503 for overload cases:
