Stagg, the point here is that your provider says:

  "most system’s don’t route the ACK based on its Request-URI when keeping
   state."

It doesn't matter what "others" do, the fact is that the provider CANNOT send 
a WRONG formed ACK by asumming that the client will handle it in a exotic way 
instead of the way RFC3261 defines (the only standard).

So the excuse of your provider is basically:
- "With other clients I have not this problem".
- "Most of them accept my ACK since they don't handle it as RFC3261 defines".

Your provider must recognice that him ACK is wrong, regardless of how you 
proxy handles it (in fact it handles it correctly). And he MUST fix it.

Pain of ignorant carriers...
