>>182 doesn't mean "call-waiting", it can mean "call-waiting", "queued"... 

It's the same thing isn't it?

If you've got a "call-waiting", then your call is queued to be answered.
And you're queuing, you're a call that is waiting to be answered.

For me, call-waiting is a type of queue (a queue of one).

So, if something is written with Unicode encoding... it becomes automatically 
readable by anyone in the world? Great, I'll talk my grandmother about it. XD

Ok, imagine that 180 and 183 don't exist. Instead an unique 101 code exists and 
the description is the reason phrase. But any device could write that 
description in whatever language (as you suggested above for 182 code) so:

  SIP/101 Ringing              <-- English
  SIP/101 Sonando              <-- Spanish
  SIP/101 Session Progress     <-- English
  SIP/101 Early Session        <-- English too
  SIP/101 En progreso          <-- Spanish

I'm sure that you don't agree with this "feature", so why do you suggest 
exactly the same for 182? Note that 182 doesn't mean "call-waiting", it can 
mean "call-waiting", "queued"...

Another possibility would take place if we all agree on the real meaning of
182: could it mean that the called has received the call but he is already on 
other call? In that case 182 would just mean "call-waiting in remote side", so 
our intelligent UAC doesn't require to "translate" the reason phrase and 
display it to the user.


Thanks.
